The McDonnell Douglas (now Boeing) F/A-18 Hornet is a twin-engine supersonic, all-weather carrier-capable multirole combat jet, designed as both a fighter and attack aircraft (F/A designation for Fighter/Attack). Designed by McDonnell Douglas and Northrop, the F/A-18 was derived from the latter's YF-17 in the 1970s for use by the United States Navy and Marine Corps. The Hornet is also used by the air forces of several other nations. The U.S. Navy's Flight Demonstration Squadron, the Blue Angels, has used the Hornet since 1986.

The F/A-18 has a top speed of Mach 1.8 (1,034 knots, 1,190 mph or 1,915 km/h at 40,000 ft or 12,190 m). It can carry a wide variety of bombs and missiles, including air-to-air and air-to-ground, supplemented by the 20 mm M61 Vulcan cannon. It is powered by two General Electric F404 turbofan engines, which give the aircraft a high thrust-to-weight ratio. The F/A-18 has excellent aerodynamic characteristics, primarily attributed to its leading edge extensions (LEX). The fighter's primary missions are fighter escort, fleet air defense, Suppression of Enemy Air Defenses (SEAD), air interdiction, close air support and aerial reconnaissance. Its versatility and reliability have proven it to be a valuable carrier asset, though it has been criticized for its lack of range and payload compared to its earlier contemporaries, such as the Grumman F-14 Tomcat in the fighter and strike fighter role, and the Grumman A-6 Intruder and LTV A-7 Corsair II in the attack role.

The Hornet saw its first combat action in 1986 during the 1986 United States bombing of Libya and subsequently participated in 1991 Gulf War and 2003 Iraq War. The F/A-18 Hornet provided the baseline design for the Boeing F/A-18E/F Super Hornet, a larger, evolutionary redesign of the F/A-18.

F-18 Hornet Papacraft Model

The Boeing F/A-18E Super Hornet and related twin-seat F/A-18F are twin-engine carrier-capable multirole fighter aircraft variants based on the McDonnell Douglas F/A-18 Hornet. The F/A-18E single-seat and F/A-18F tandem-seat variants are larger and more advanced derivatives of the F/A-18C and D Hornet. The Super Hornet has an internal 20 mm M61 rotary cannon and can carry air-to-air missiles and air-to-surface weapons. Additional fuel can be carried in up to five external fuel tanks and the aircraft can be configured as an airborne tanker by adding an external air refueling system.
Designed and initially produced by McDonnell Douglas, the Super Hornet first flew in 1995. Full-rate production began in September 1997, after the merger of McDonnell Douglas and Boeing the previous month. The Super Hornet entered service with the United States Navy in 1999, replacing the Grumman F-14 Tomcat, which was retired in 2006; the Super Hornet serves alongside the original Hornet. The Royal Australian Air Force (RAAF), which has operated the F/A-18A as its main fighter since 1984, ordered the F/A-18F in 2007 to replace its aging F-111 fleet. RAAF Super Hornets entered service in December 2010.

Development

Origins

The Super Hornet is an evolutionary redesign of the McDonnell Douglas F/A-18 Hornet. The Super Hornet's unique wing and tail configuration can be traced back to an internal Northrop project P-530, c. 1965; this had started as a substantial rework of the lightweight F-5E with a larger wing, twin tail fins and a distinctive leading edge root extension (LERX).[5] Later flying as the Northrop YF-17 "Cobra", it competed in the United States Air Force's Lightweight Fighter (LWF) program to produce a smaller and simpler fighter to complement the larger F-15 Eagle. The Navy directed that the YF-17 be redesigned into the larger F/A-18 Hornet to meet a requirement for a multi-role fighter to complement the larger F-14 Tomcat serving in air superiority and fleet defense interceptor roles. The Hornet proved to be effective but limited in combat radius. Its design was expanded in the Super Hornet, which has an empty weight slightly greater than the F-15C.[6]
The concept of an enlarged Hornet was first proposed in 1980s, which was marketed by McDonnell Douglas as Hornet 2000. The Hornet 2000 concept was an advanced F/A-18 with a larger wing and a longer fuselage to carry more fuel and more powerful engines.[7] In January 1988, the Hornet 2000 study was officially announced.[8] At the same time, U.S. Naval Aviation faced a number of problems; the McDonnell Douglas A-12 Avenger II, which was intended to replace the obsolete Grumman A-6 Intruder and LTV A-7 Corsair II, was cancelled after the program ran into serious problems. The end of the Cold War led to a period of military budget cuts and considerable restructuring.[9] The Navy considered updating an existing design as a more attractive approach to a clean-sheet program. As an alternative to the A-12, McDonnell Douglas proposed the "Super Hornet" (initially "Hornet II" in the 1980s), an improvement of the successful early F/A-18 models,[8] which could serve as an alternate replacement for the A-6 Intruder. At the same time, the Navy needed a fleet defense fighter to replace the canceled Navy Advanced Tactical Fighter (NATF), which would have been a navalized variant of the Air Force's Lockheed Martin F-22 Raptor.[7]

Testing and production

The Super Hornet was first ordered by the U.S. Navy in 1992, in part to replace the F-14 Tomcat; all naval combat jets were on Hornet variants until the introduction of the F-35C Lightning II.[10] The Navy retained the F/A-18 designation to help sell the program to Congress as a low-risk "derivative", though the Super Hornet is largely a new aircraft. The Hornet and Super Hornet share many characteristics, including avionics, ejection seats, radar, armament, mission computer software, and maintenance/operating procedures. The initial F/A-18E/F retained most of the avionics systems from the F/A-18C/D's configuration at the time.[7]
The Super Hornet first flew on 29 November 1995.[7] Initial production on the F/A-18E/F began in 1995. Flight testing started in 1996 with the F/A-18E/F's first carrier landing in 1997.[7] Low-rate production began in March 1997[11] with full production beginning in September 1997.[12] Testing continued through 1999, finishing with sea trials and aerial refueling demonstrations. Testing involved 3,100 test flights covering 4,600 flight hours.[8] The Super Hornet underwent U.S. Navy operational tests and evaluations in 1999,[13] and was approved in February 2000.[14]
The Navy considers the Super Hornet's acquisition a success, meeting cost, schedule, and weight (400 lb, 181 kg below) requirements.[15] While having the same general layout and systems, the Super Hornet differs in many ways from the original F/A-18 Hornet. The Super Hornet is informally referred to as the "Rhino" to distinguish it from earlier "legacy" Hornets and to prevent confusion in radio calls. This aids safe flight operations, as the catapult and arresting systems must be set differently for the heavier Super Hornet. (The "Rhino" nickname was earlier used by the McDonnell Douglas F-4 Phantom II, which was retired from the fleet in 1987.)

As of 2014, the U.S. Navy flies both the F/A-18E single-seater and F/A-18F two-seater in combat roles, taking the place of the retired F-14, A-6 Intruder, Lockheed S-3 Viking, and KA-6D. An electronic warfare variant, the EA-18G Growler, replaces the EA-6B Prowler. The Navy calls this reduction in aircraft types a "neck-down". In the Vietnam War era, the Super Hornet's roles were performed by a combination of the A-1/A-4/A-7 (light attack), A-6 (medium attack), F-8/F-4 (fighter), RA-5C (recon), KA-3/KA-6 (tanker) and EA-6 (electronic warfare). It is anticipated that $1 billion in fleetwide annual savings will result from replacing other types with the Super Hornet.[16]
In 2003, the Navy identified a flaw present in the under wing pylons across the Super Hornet fleet which required remedial repairs, or would otherwise decrease the aircraft's service life. As of 2007, changes to rectify the problem on newly manufactured airframes had been implemented, and existing aircraft would also receive modifications from 2009 onwards.[17]

Improvements and changes

The Block II Super Hornet incorporates an improved Active Electronically Scanned Array (AESA) radar, larger displays, the joint helmet mounted cuing system, and several other avionics replacements.[18][19] Avionics and weapons systems that were under developement for the prospective production version of the Boeing X-32 were used on the Block II Super Hornet.[20] New-build aircraft received the APG-79 AESA radar beginning in 2005.[18] In January 2008, it was announced that 135 earlier production aircraft were to be retrofitted with AESA radars.[21]
In 2008, Boeing discussed the development of a Super Hornet Block III with the U.S. and Australian military, featuring additional stealth capabilities and extended range.[22] In 2010, Boeing offered prospective Super Hornet customers the "International Roadmap", which included conformal fuel tanks, enhanced engines, an enclosed weapons pod (EWP), a next-generation cockpit, a new missile warning system, and an internal infra-red search and track (IRST) system.[23][24] The EWP has four internal stations for munitions, a single aircraft can carry a total of three EWPs, housing up to 12 AMRAAMs and 2 Sidewinders.[25][26] The next-generation cockpit features a 19 x 11 inch touch-sensitive display.[27] In 2011, Boeing received a US Navy contract to develop a new mission computer.[28]
In 2007, Boeing stated that a passive Infrared Search and Track (IRST) sensor would be an available future option. The sensor, mounted in a modified centerline fuel tank, detects long wave IR emissions to spot and track targets such as aircraft;[29] combat using the IRST and AIM-9X Sidewinder missiles is immune to radar jamming.[30] In May 2009, Lockheed Martin announced its selection by Boeing for the IRST's technology development phase,[31] a contract followed in November 2011.[32] As of September 2013, a basic IRST would be fielded in 2016 and a longer-range version in 2019; sequestration cuts in 2013 could cause two years of delays.[30]
An F/A-18F Super Hornet named the "Green Hornet", during a supersonic test flight in 2010.
Boeing and Northrop Grumman self-funded a prototype of the Advanced Super Hornet.[33] The prototype features a 50% reduction in frontal radar cross-section (RCS), conformal fuel tanks (CFT), and an enclosed weapons pod.[34][35] Features could also be integrated onto the EA-18G Growler; using CFTs on the EA-18 fleet was speculated as useful to releasing underwing space and drag margin for the Next Generation Jammer.[36][37] Flight tests of the Advanced Super Hornet began on 5 August 2013 and continued for three weeks, testing the performance of CFTs, the enclosed weapons pod (EWP), and signature enhancements.[38] The U.S. Navy was reported pleased with the Advanced Super Hornet's flight test results, and hopes it will give lawmakers options in future procurements.[39]
In March 2013, the U.S. Navy was considering the widespread adoption of conformal fuel tanks, which would allow the Super Hornet to carry 3,500 lb (1,600 kg) of additional fuel. Budgetary pressures from the F-35C Lightning II and Pacific region operations were cited as reasons supporting the use of CFTs. Flight testing demonstrated CFTs could slightly reduce drag while expanding the combat radius by 260 nautical miles.[40] The prototype CFT weighed 1,500 lb, production CFTs are expected to weigh 870 lb. Boeing stated that the CFTs do not add any cruise drag but acknowledged a negative impact imposed on transonic acceleration due to increased wave drag. General Electric's enhanced performance engine (EPE), increasing the F414-GE-400's power output from 22,000 lb to 26,400 lb of thrust per engine, was suggested as a mitigating measure.[41] In 2009, development commenced on several engine improvements, including greater resistance to foreign object damage, reduced fuel burn rate, and potentially increased thrust of up to 20%.[42][43]
Boeing has conceptualized a Super Hornet hybrid, to be equipped with the EA-18G Growler's electronic signal detection capabilities, giving it the ability to engage targets seen using the receiver; Boeing's concept did not include the ALQ-99 jamming pod. Growth capabilities could include the addition of a long-range infrared search and track sensor and new air-to-air tracking modes.[44]

Design

Overview

The Super Hornet is largely a new aircraft. It is about 20% larger, 7,000 lb (3,200 kg) heavier empty weight, and 15,000 lb (6,800 kg) heavier maximum weight than the original Hornet. The Super Hornet carries 33% more internal fuel, increasing mission range by 41% and endurance by 50% over the "Legacy" Hornet. The empty weight of the Super Hornet is about 11,000 lb (5,000 kg) less than that of the F-14 Tomcat which it replaced, while approaching, but not matching, the F-14's payload and range.[45][N 2]
The Super Hornet, unlike the previous Hornet, is designed so it can be equipped with an aerial refueling system (ARS) or "buddy store" for the refueling of other aircraft,[46] filling the tactical airborne tanker role the Navy had lost with the retirement of the KA-6D and Lockheed S-3B Viking tankers. The ARS includes an external 330 US gal (1,200 L) tank with hose reel on the centerline, along with four external 480 US gal (1,800 L) tanks and internal tanks, for a total of 29,000 lb (13,000 kg) of fuel on the aircraft.[46][47] On typical missions a fifth of the air wing is dedicated to the tanker role, which consumes aircraft fatigue life expectancy faster than other missions.[48]

Airframe changes

The forward fuselage is unchanged, but the remainder of the aircraft shares little with earlier F/A-18C/D models. The fuselage was stretched by 34 in (86 cm) to make room for fuel and future avionics upgrades and increased the wing area by 25%.[49] However, the Super Hornet has 42% fewer structural parts than the original Hornet design.[50] The General Electric F414 engine, developed from the Hornet's F404, has 35% additional thrust over most of the aircraft's flight envelope.[49][51] The Super Hornet can return to an aircraft carrier with a larger load of unspent fuel and munitions than the original Hornet. The term for this ability is known as "bringback". Bringback for the Super Hornet is in excess of 9,000 lb (4,100 kg).[52]
Other differences include approximately rectangular intakes for the engines and two extra wing hard points for payload (for a total of 11), retaining previous hardpoints on the bottom centerline, wingtips, and two conformal fuselage positions.[53] Among the most significant aerodynamic changes are the enlarged leading edge extensions (LEX) which provide improved vortex lifting characteristics in high angle of attack maneuvers, and reduce the static stability margin to enhance pitching characteristics. This results in pitch rates in excess of 40 degrees per second, and high resistance to departure from controlled flight.[54]

Radar signature reduction measures

Survivability is an important feature of the Super Hornet design. The U.S. Navy took a "balanced approach" to survivability in its design.[55] This means that it does not rely on low-observable technology, such as stealth systems, to the exclusion of other survivability factors. Instead, its design incorporates a combination of stealth, advanced electronic-warfare capabilities, reduced ballistic vulnerability, the use of standoff weapons, and innovative tactics that cumulatively and collectively enhance the safety of the fighter and crew.[56]

The F/A-18E/F's radar cross-section was reduced greatly from some aspects, mainly the front and rear.[7] The design of the engine inlets reduces the aircraft's frontal radar cross-section. The alignment of the leading edges of the engine inlets is designed to scatter radiation to the sides. Fixed fanlike reflecting structures in the inlet tunnel divert radar energy away from the rotating fan blades.[57]
The Super Hornet also makes considerable use of panel joint serration and edge alignment. Considerable attention has been paid to the removal or filling of unnecessary surface join gaps and resonant cavities. Where the F/A-18A-D used grilles to cover various accessory exhaust and inlet ducts, the F/A-18E/F uses perforated panels that appear opaque to radar waves at the frequencies used. Careful attention has been paid to the alignment of many panel boundaries and edges, to direct reflected waves away from the aircraft in uniformly narrow angles.[7]
It is claimed that the Super Hornet employs the most extensive radar cross section reduction measures of any contemporary fighter, other than the F-22 and F-35. While the F/A-18E/F is not a true stealth fighter like the F-22, it will have a frontal radar cross-section an order of magnitude smaller than prior generation fighters.[57] Additional RCS reduction measures can be installed on an as-needed basis.[58]

Avionics

Initially, the Super Hornet's avionics and software had a 90% commonality with that of the F/A-18C/D fleet at the time.[51] Differences include a touch-sensitive, up-front control display; a large liquid-crystal multipurpose color display; and a fuel display.[51] The Super Hornet has a quadruplex digital fly-by-wire system,[59] as well as a digital flight-control system that detects and corrects for battle damage.[54] Initial production models used the APG-73 radar, later replaced by the APG-79 Active Electronically Scanned Array (AESA).[18][19] The AN/ASQ-228 ATFLIR (Advanced Targeting Forward Looking InfraRed), is the main electro-optical sensor and laser designator pod for the Super Hornet. The communications equipment consist of an AN/ARC-210 VHF/UHF radio[60] and a MIDS low volume terminal for HAVE QUICK, SINCGARS and Link 16 connectivity.
The defensive countermeasures of Block I aircraft includes the AN/ALR-67(V)3 radar warning receiver, the AN/ALE-47 countermeasures dispenser, the AN/ALE-50 towed decoy and the AN/ALQ-165 Airborne Self-Protect Jammer (ASPJ). Block II aircraft replace the ALQ-165 with the AN/ALQ-214 Integrated Defensive Countermeasures (IDECM) system, consisting of internally mounted threat receivers and optional self-protection jammers. Interior and exterior lighting on the Block II was changed to allow the use of night vision goggles (NVG). The older ALE-50 decoys are being replaced by ALE-55 towed decoys, which can transmit jamming signals based on data received from the IDECM.[61] The improved AN/ALQ-214 jammer was added on Block II aurcraft.[19]
Block II aircraft were fitted with the APG-79 AESA radar, capable of executing simultaneous air-to-air and air-to-ground attacks, and providing higher quality high-resolution ground mapping at long standoff ranges.[62] The AESA radar can also detect smaller targets, such as inbound missiles[63] and can track air targets beyond the range of the aircraft's air to air missiles.[64] VFA-213, the first Super Hornet squadron to fly AESA-equipped Super Hornets, became "safe for flight" (independently fly and maintain the F/A-18F) on 27 October 2006.[65] The first Super Hornet upgraded with the Joint Helmet Mounted Cueing System (JHMCS) was delivered to VFA-213 on 18 May 2007.[66] The JHMCS provides multi-purpose situational awareness, which includes high-off-bore-sight missile cuing. The Shared Reconnaissance Pod (SHARP) is a high-resolution, digital tactical air reconnaissance system that features advanced day/night and all-weather capability.[67] The Multifunctional Information Distribution System low volume communication terminal is being upgraded with the MIDS-JTRS system,[68] which will allow a tenfold increase in bandwidth as well as compatibility with the Joint Tactical Radio System standards.[69]

Operational history

United States Navy

F/A-18E Super Hornet launching from Abraham Lincoln
An F/A-18E Super Hornet prepares to land on the flight deck of the aircraft carrier USS George H.W. Bush (CVN 77).
The Super Hornet achieved initial operating capability (IOC) in September 2001 with the U.S. Navy's Strike Fighter Squadron 115 (VFA-115) at Naval Air Station Lemoore, California.[15] VFA-115 was also the first unit to take their F/A-18 Super Hornets into combat. On 6 November 2002, two F/A-18Es conducted a "Response Option" strike in support of Operation Southern Watch on two surface-to-air missile launchers at Al Kut, Iraq and an air defense command and control bunker at Tallil air base. One of the pilots, Lieutenant John Turner, dropped 2,000 lb (910 kg) JDAM bombs from the Super Hornet for the first time during combat.[70]
In support of Operation Iraqi Freedom (Iraq War), VFA-14, VFA-41 and VFA-115 flew close air support, strike, escort, SEAD and aerial refueling sorties. Two F/A-18Es from VFA-14 and two F/A-18Fs from VFA-41 were forward deployed to the Abraham Lincoln. The VFA-14 aircraft flew mostly as aerial refuelers and the VFA-41 fighters as Forward Air Controller (Airborne) or FAC(A)s. On 6 April 2005, VFA-154 and VFA-147 (the latter squadron then still operating F/A-18Cs) dropped two 500-pound (230 kg) laser-guided bombs on an enemy insurgent location east of Baghdad.[71]

On 8 September 2006, VFA-211 F/A-18F Super Hornets expended GBU-12 and GBU-38 bombs against Taliban fighters and Taliban fortifications west and northwest of Kandahar. This was the first time the unit had participated in an active combat capacity using the Super Hornet.[72][73]
During the 2006–2007 cruise with Dwight D. Eisenhower, VFA-103 and VFA-143 supported Operations Iraqi Freedom, Enduring Freedom and operations off the Somali coast. Alongside "Legacy Hornet" squadrons, VFA-131 and VFA-83, they dropped 140 precision guided weapons and performed nearly 70 strafing runs.[74]
In 2007, Boeing proposed additional F/A-18E/Fs to the U.S. Navy in a multi-year contract.[75] As of October 2008, Boeing had delivered 367 Super Hornets to the U.S. Navy.[76] On 6 April 2009, Defense Secretary Gates announced that the Department of Defense intended to acquire 31 F/A-18s in FY2010.[77] Congress requested the DoD study a further multi-year contract so that a projected fighter shortfall could be averted;[78] in 2006, the Navy was 60 fighters below its validated aircraft requirement.[79] The FY2010 budget bill authorized a multiyear purchase agreement for additional Super Hornets.[80][81] A multi-year contract was finalized on 28 September 2010, reported as saving $600 million over individual yearly contracts, for 66 Super Hornets and 58 Growlers to mitigate a four-year delay in the F-35 program.[82]
F/A-18Fs being refueled over Afghanistan in 2010
On 7 August 2014, U.S. defense officials announced they had authorizated to launch bombing missions upon Islamic State forces in northern Iraq. The decision to take direct action was made to protect U.S. personnel in the city of Irbil and to ensure the safety of transport aircraft making airdrops to Yazidi civilians. Early on 8 August 2014, two Super Hornets took off from the USS George H.W. Bush and dropped 500 lb laser-guided bombs on a "mobile artillery piece" the militants had been using to shell Kurdish forces defending the city.[83][84] Later that day, four more aircraft struck a seven-vehicle convoy and a mortar position.[85]

Royal Australian Air Force

On 3 May 2007, the Australian Government signed a A$2.9 billion contract to acquire 24 F/A-18Fs for the Royal Australian Air Force (RAAF) as an interim replacement for the aging F-111s.[86] The total cost with training and support over 10 years is A$6 billion (US$4.6 billion).[87] The order was controversial. Air Vice Marshal (ret.) Peter Criss, a former Air Commander, said he was "absolutely astounded" that $6 billion would be spend on an interim aircraft,[88] and cited evidence given by the U.S. Senate Armed Services Committee that the Super Hornet Block I's specific excess power is inferior to the MiG-29 and Su-30 being operated, or ordered, by multiple air forces in South East Asia.[89] Air Commodore (ret.) Ted Bushell stated that the F/A-18F could not perform the role assigned by the Australian government, and the F-111 was suitable for the strategic deterrent/strike role until at least 2020.[88] Some critics claimed the F/A-18F purchase may ease additional Australian Super Hornet sales, particularly if the F-35 program ran into more difficulty.[90]
An RAAF F/A-18F shortly after it first arrived in Australia
A review was announced on 31 December 2007, by the new Australian Labor government, as part of a wider review of the RAAF's combat aircraft procurement plans. The main reasons given were concerns over operational suitability, the lack of a proper review process, and internal beliefs that an interim fighter was not required.[91] On 17 March 2008, the Government announced that it would proceed with plans to acquire all 24 F/A-18Fs.[92] Defence Minister Joel Fitzgibbon said that the Super Hornet was an "excellent aircraft";[92] he also indicated that costs and logistical factors contributed to the decision: the F-111's retirement was "irreversible"; "only" the F/A-18F could meet the timeframe and that cancellation "would bring significant financial penalties and create understandable tensions between the contract partners."[93][94]
The Block II package aircraft offered to the RAAF include installed engines and six spares, APG-79 AESA radars, Link 16 connectivity, LAU-127 guided missile launchers, AN/ALE-55 fiber optic towed decoys and other equipment.[95] The government has also sought U.S. export approval for Boeing EA-18G Growlers.[96] On 27 February 2009, Fitzgibbon announced that 12 of the 24 Super Hornets would be wired on the production line for future modification as EA-18Gs. The additional wiring would cost A$35 million. The final decision on conversion to EA-18Gs, at a cost of A$300 million, would be made in 2012.[97]
A RAAF Super Hornet at the 2013 Avalon Airshow
The first RAAF Super Hornet was completed in 2009 and first flew from Boeing's factory in St. Louis, Missouri on 21 July 2009.[98] RAAF pilots and air combat officers began training in the USA in 2009, with No. 1 Squadron planned to become fully operational with the F/A-18F in 2010. The RAAF's first five Super Hornets arrived at their home base, RAAF Base Amberley in Queensland, on 26 March 2010.[99] These initial aircraft were joined by six more aircraft on 7 July 2010.[100] With the arrival of another four aircraft in December 2010, the first RAAF F/A-18F squadron was declared operational on 9 December 2010.[101]
In December 2012, the Australian government sought information from the United States government about the cost of acquiring a further 24 F/A-18Fs. These aircraft may be purchased to avoid a capability gap developing due to delays to the F-35 program.[102] In February 2013, the U.S. Defense Security Cooperation Agency notified Congress of a possible Foreign Military Sale to Australia for up to 12 F/A-18E/F Super Hornet and 12 EA-18G Growler aircraft with associated equipment, parts, training and logistical support.[103] In May 2013, Australia announced they would keep the 24 F/A-18F Super Hornets they currently have instead of converting them, and will order 12 new-built EA-18G Growlers. The government remains committed to the F-35 Lightning II acquisition.[104]
On 24 September 2014, eight RAAF Super Hornets, along with a tanker, an early warning aircraft, and 400 personnel arrived in the United Arab Emirates to take part in operations against Islamic State militants. The Super Hornets were ready to commence attacks once ordered.[105] On 5 October 2014, the RAAF officially started combat missions over Iraq, with a pair of F/A-18F Super Hornets armed with weapons including GPS guided bombs; they returned safely to base without attacking targets. A RAAF KC-30A refuelling aircraft supported the Super Hornets mission.[106][107] Australia conducted its first attack against Islamic State forces on 8 October 2014, when a Super Hornet dropped two bombs on an "ISIL facility" in northern Iraq.[108]

Potential operators

The United States Marine Corps has avoided the Super Hornet program and their resistance is so high that they would rather fly former Navy F/A-18Cs that have been replaced with Super Hornets. This is said to be because they fear that any Super Hornet buys will be at the cost of the F-35B STOVL fighters that they intend to operate from amphibious ships.[109] As a concession, the Marine Corps has agreed to eventually equip five Marine fighter-attack squadrons (VMFA) with the F-35C carrier variant to continue to augment Navy carrier air wings as they currently do with the F/A-18C.[110]

Boeing offered Malaysia the Super Hornets as part of a buy-back package for its existing F/A-18 Hornets in 2002. However, the Super Hornet procurement was halted in 2007 after the government decided to purchase the Sukhoi Su-30MKM instead. But Chief Gen. Datuk Nik Ismail Nik Mohamaed of the Royal Malaysian Air Force (RMAF) indicated that the air force had not planned to end procurement of the Super Hornets, instead saying that it needed such fighters.[111] In a separate deal, the RMAF's MiG-29 will be replaced in 2015. The F/A-18F Super Hornet is one of the leading contenders for the MiG-29 replacement MRCA program. Under the program, the RMAF is looking to equip three squadrons with 36 to 40 new fighter aircraft with an estimated budget of RM6 billion to RM8 billion (US$1.84 billion to US$2.46 billion). The other competitors are the Eurofighter Typhoon, Dassault Rafale and Saab JAS 39 Gripen.[112]
Boeing proposed the Super Hornet to the Brazilian government. It was reported that the Super Hornet was selected as one of three finalists in Brazil's fighter competition in October 2008. Brazil has put forward an initial requirement for 36 aircraft, with a potential total purchase of 120 examples.[76][113] However news of NSA's spying activity on Brazilian leaders has caused animosity between Brazil and the US.[114] Brazil eventually dropped the Super Hornet from its final list and selected the Saab JAS 39 Gripen in December 2013.[115]
In 2008, the Royal Danish Air Force was offered the Super Hornet.[116] The Super Hornet is one of three fighter aircraft in a Danish competition to replace 48 F-16AM/BMs.[117][118] The other contenders are Lockheed Martin's F-35A Joint Strike Fighter and the Eurofighter Typhoon. Denmark is a level-3 partner in the JSF program, and has invested US$200 million so far. The final selection is to be in mid-2015 where 24 to 30 fighters are expected.[119] In April 2014, the Danish Ministry of Defence handed over a Request for Binding Information (RBI) that specifically listed the F/A-18F two-seat variant.[120]

For India's MMRCA competition, Boeing offered a customized variant called F/A-18IN, which included Raytheon's APG-79 AESA radar.[121] In August 2008, Boeing submitted an industrial participation proposal to India describing partnerships with companies in India.[122] The Indian Air Force (IAF) extensively evaluated the Super Hornets and conducted field trials in August 2009.[123] However, in April 2011, the IAF rejected F/A-18IN's bid in favor of the Eurofighter Typhoon and Dassault Rafale.[124]
On 10 March 2009, Boeing offered the Super Hornet for Greece's Next-Generation Fighter Program.[125]
On 1 August 2010, The Sunday Times reported that the British government was considering canceling orders for the Lockheed Martin F-35 Lightning II and buying the Super Hornet instead for its Queen Elizabeth class aircraft carriers. It was stated that this would save the UK defense budget about £10 billion. An industry source suggested that the Super Hornet could be ski jump launched without catapults.[126] The UK has reverted to a STOVL aircraft carrier equipped with F-35B fighters.
The United Arab Emirates has asked for information on the Super Hornet.[127]
Boeing stated that the "stealth characteristics" of the Super Hornet were ignored in Canada's sole source selection of the F-35.[128] In April 2012, Canada was reviewing its plans to procure the F-35 and may consider buying the Super Hornet instead.[129] In September 2013, Boeing provided Canada with cost and capability data for its Advanced F/A-18 Super Hornet, suggesting that a fleet of 65 aircraft would cost $1.7 billion less than a fleet of F-35s. The Advanced Super Hornet builds upon the existing Super Hornet, which is an improvement of the current CF-18 Hornet. The U.S. Navy buys Super Hornets for $52 million per aircraft, while the advanced version would add $6–$10 million per aircraft, depending on options selected.[130]
In early 2011, Bulgaria was considering the F/A-18 Super Hornet, among other aircraft, as a replacement for its MiG-21 fleet.[131]
Boeing offered the Super Hornet to the Swiss Air Force as a replacement for Swiss F-5E Tigers, then withdrew from the competition.[132]
On 12 March 2014, Belgian newspaper De Morgen reported that Boeing is in talks with the Belgian Defence ministry about the Super Hornet as a candidate to replace Belgium's aging F-16 fleet.[133]
Poland is planning to purchase 64 multirole combat aircraft from 2021 as part of that country's modernization plans. The new fighters will replace the Polish Air Force's fleet of Sukhoi Su-22M4 ground attack aircraft and Mikoyan MiG-29 fighter aircraft. The planned open tender procedure could include the F-35 Lightning II, JAS 39 Gripen E/F, the newest variants of Eurofighter Typhoon and Dassault Rafale, and Boeing's F/A-18E/F Advanced Super Hornet.[134][135][136][137]

Program future

Boeing is addressing the realistic possibility that the Super Hornet production line will close in 2017. Because orders for the F-15 have also dwindled, Boeing is readying plans to close its St. Louis factory that makes both airplanes. Chris Chadwick, president of Boeing Defense, Space and Security, told the Wall Street Journal that, although "we're still solidly behind them," the company may decide by April 2015 whether to shut down both assembly lines and close the factory.[138]

Variants

The Special Type 2 Launch Ka-Mi (特二式内火艇 カミ Toku-ni-shiki uchibitei kami?) was the Imperial Japanese Navy's first amphibious tank. The Type 2 Ka-Mi was based on the Imperial Japanese Army's Type 95 Ha-Go light tank with major modifications, and was a capable armoured fighting vehicle on both land and at sea.[1]

History and development


Type 2 Ka-Mi tanks without their flotation devices fitted
As early as 1928, the Japanese Army had been developing and testing amphibious tanks and created several experimental models such as the SR-II, the Type 1 Mi-Sha and the Type 92 A-I-Go which either never made it off the drawing board or were produced only as one-off prototypes for concept testing. In 1940, The Navy took over development of amphibious vehicles and two years later came up with the Type 2 Ka-Mi. The Type 2 Ka-Mi was designed for the Navy's Special Naval Landing Forces for the amphibious invasion of Pacific Islands without adequate port facilities, and for various special operations missions.
Only 184 units of the Type 2 Ka-Mi were built, beginning in 1942, due to the number of complex components and due to the fact that it had to be nearly completely hand-built.[2]


Design

The Type 2 Ka-Mi was based on the Army's Type 95 Ha-Go light tank, but with an all-welded hull with rubber seals in place of the riveted armor. It was intended to be water-tight. Large, hollow pontoons made from steel plates were attached to the front glacis plate and rear decking to give the necessary buoyancy. The front pontoon was internally divided into eight separate compartments to minimize the effects of damage from flooding and shellfire. These flotation devices could be jettisoned from inside the tank once the tank landed and commenced ground combat operations.
The Type 2 Ka-Mi's gun turret with a high-velocity Type 1 37 mm gun and a coaxial Type 97 light machine gun was able to rotate 360°. A second Type 97 light machine gun was located in the tank's bow. Occasionally Type 2 Ka-Mi's were armed with a pair of naval torpedoes; one on either side of the hull. The Type 2 Ka-Mi could also be launched from the deck of a submarine.[3]
The Type 2 Ka-Mi was capable of attaining speeds of 10 km/h in the water with a range of 150 km through two propellers situated at the rear of the hull, powered by the tank's engine. Steering was in the control of the tank commander, who operated a pair of rudders from the turret through cables.
That the crew included an onboard mechanic is an indication of the complexity of the design.

Combat Record

The Type 2 Ka-Mi came into active service after the initial campaigns of World War II, and was thus too late to be used in its original design mission of amphibious landings. Many units were assigned to naval garrison detachments in the South Pacific Mandate and in the Netherlands East Indies.
The Type 2 Ka-Mi was encountered by the United States Marine Corps in the Marshall Islands and Mariana Islands, particularly on Guam, where it was dug into the ground and misused in static defense positions. It was also encountered in combat by U.S. Army forces at Aitape and Biak during the New Guinea campaign and during the fighting on the Philippine island of Leyte in late 1944. According to Ralph Zumbro in his book 'Tank Aces',several Ka-Mi were destroyed by Army LVT-1s off the coast of Leyte during history's only Amtank vs. Amtank action. A handful more were captured by Army troops on Luzon in 1945,but had not entered combat. A number of photos exist of these vehicles, as well as several others captured by Australian and Commonwealth troops. In common with most Japanese armor, it was no match for Allied tanks or anti-armor weapons.[2]

Surviving Vehicles

The Kubinka Tank Museum in Moscow, Russia has a Type 2 Ka-Mi on display, complete with its front and rear pontoons.
A near complete hull is located in the bush near the airport on Babeldaob, Palau. Another interesting specimen is located in Koror area, Palau, between the Police Station and the Civic center. It's very interesting as it still has a heavy anti aircraft machinegun on the rear pontoon
