A-10 Thunderbolt II by Fairchild

Great shot of an A-10 over Afghanistan.  In this picture, Capt. Andrew Quinn flies his OA/A-10 Thunderbolt II observation/attack aircraft to a refueling position behind a KC-135 Stratotanker.  This picture was taken  on Sunday, March 26, 2006 by U.S. Air Force photo/Master Sgt. Lance Cheung.  Captain Quinn is currently deployed to the 355th Expeditionary Fighter Squadron at Bagram Air Base, Afghanistan.   The A-10 Thunderbolt II is a single-seat, twin-engine, straight-wing jet aircraft designed to provide close air support (CAS) of ground forces.

It was the first U.S. Air Force aircraft, designed in the 1970′s, exclusively for close air support . The A-10′s official name comes from the Republic P-47 Thunderbolt of World War II, a fighter that was particularly effective at close air support. The A-10 is more commonly known by its nickname “Warthog” or simply “Hog”.

Fairchild Republic A-10 Thunderbolt II “WartHog”

 

The Fairchild Republic A-10 Thunderbolt II is also known as the Warthog, the Flying Gun and the Tankbuster. The A-10 and OA-10 Thunderbolt IIs are the first Air Force aircraft specially designed for close air support of ground forces. They are simple, effective and survivable twin-engine jet aircraft that can be used against all ground targets, including tanks and other armored vehicles. The primary mission of the A-10 is to provide day and night close air combat support for friendly land forces and to act as forward air controller (FAC) to coordinate and direct friendly air forces in support of land forces. The A-10 has a secondary mission of supporting search and rescue and Special Forces operations. It also possesses a limited capability to perform certain types of interdiction. All of these missions may take place in a high or low threat environment

The A/OA-10 aircraft was specifically developed as a close air support aircraft with reliability and maintainability as major design considerations. The Air Force requirements documents emphasized payload, low altitude flying capability, range and loiter capability, low speed maneuverability and weapons delivery accuracy. The A-10 is slow enough to be an observation plane. This greatly increases the A-10′s effectiveness at protecting ground troops. The aircraft is suitable for operation from forward air bases, with short take-off and landing capability. The aircraft has a long range (800 miles) and endurance and can loiter in the battle area.

The A/OA-10 is a single place, pressurized, low wing and tail aircraft with two General Electric TF-34-100/A turbo-fan engines, each with a sea level static thrust rating of approximately 9000 pounds. The engines are installed in nacelles mounted on pylons extending from the fuselage just aft of and above the wing. Two vertical stabilizers are located at the outboard tips of the horizontal stabilizers. The forward retracting tricycle landing gear incorporates short struts and a wide tread. The nose wheel retracts fully into the fuselage nose. The main gear retracts into streamlined fairing on the wing with the lower portion of the wheel protruding to facilitate emergency gear-up landings.

The A-10′s survivability in the close air support arena greatly exceeds that of previous Air Force aircraft. The A-10 is designed to survive even the most disastrous damage and finish the mission by landing on an unimproved airfield. Specific survivability features include titanium armor plated cockpit, redundant flight control system separated by fuel tanks, manual reversion mode for flight controls, foam filled fuel tanks, ballistic foam void fillers, and a redundant primary structure providing “get home” capability after being hit.
All of the A-10′s glass is bulletproof and the cockpit itself is surrounded by a heavy tub of titanium. Titanium armor protects both the pilot and critical areas of the flight control system. This titanium “bathtub” can survive direct hits from armor-piercing and high explosive projectiles up to 37mm in size. The front windscreen can withstand up to a 23mm projectile. Fire retardant foam protects the fuel cells which are also self sealing in the event of puncture.

The redundant primary structural sections allow the aircraft to enjoy better survivability during close air support than did previous aircraft. Designers separated all of the crucial battle and flight systems. Manual systems back up their redundant hydraulic flight-control systems. This permits pilots to fly and land when hydraulic power is lost. The wheels can roll in their pods, which lets the plane perform belly landings without significant damage to the aircraft. Dual engines are mounted away from the Warthog’s fuselage; if one is destroyed, the other can propel the craft to safety. Dual vertical stabilizers shield the hot exhaust from Russian-designed heat seeking missiles. The A-10 has two hydraulic flight control systems, backed up by a manual flight control system. This redundancy allows the pilot to control a battle damaged aircraft, even after losing all hydraulic power. Furthermore, redundant primary structural and control surfaces enhance survivability. Lastly, the long low-set wings are designed to allow flight, even if half a wing is completely blown off. No other modern aircraft can survive such punishment. The wings themselves are set low to allow for more weaponry to fit beneath the aircraft.

The General Electric Aircraft Armament Subsystem A/A49E-6 (30 millimeter Gun System) is located in the forward nose section of the fuselage. The gun system consists of the 30mm Gatling gun mechanism, double-ended link-less ammunition feed, storage assembly and hydraulic drive system. The General Electric GAU-8/A 30mm seven barrel cannon, specifically designed for the A-10, provides unmatched tank killing capability. The gun fires armor-piercing depleted uranium projectiles capable of penetrating heavy armor. It also fires a high explosive incendiary round, which is extremely effective against soft skinned targets like trucks. The cannon fires at a rate of 4,200 rounds per minute.

The A-10/OA-10 have excellent maneuverability at low air speeds and altitude, and are highly accurate weapons-delivery platforms. The A-10 has half the turning radius of the Air Force’s other primary CAS aircraft, the F-16. After initially leaving a target, the A-10 can turn around and hit the same target again, all in around 7 seconds. Due to its large combat radius, the Thunderbolt II can loiter for extended periods of time, allowing for the coordination required to employ within yards of friendly forces. They can operate under 1,000-foot ceilings (300 meters) with 1.5-mile (2.4 kilometers) visibility. Using night vision goggles, A-10/ OA-10 pilots can conduct their missions during darkness. The A-10s highly accurate weapons delivery system makes it effective against all ground targets including tanks and other armored vehicles.

The Thunderbolt II can employ a wide variety of conventional munitions, including general purpose bombs, cluster bomb units, laser guided bombs, joint direct attack munitions or JDAM), wind corrected munitions dispenser or WCMD, AGM-65 Maverick and AIM-9 Sidewinder missiles, rockets, illumination flares, and the GAU-8/A 30mm cannon, capable of firing 3,900 rounds per minute to defeat a wide variety of targets including tanks.

The first flight of the A-10 was in May 1972, and a total of 707 aircraft have since been produced. Originally manufactured by Fairchild, since 1987 the prime contractor for the A-10 has been Northrop Grumman, which carries out support and structural upgrade programmes from the Integrated Systems and Aerostructures Divisions at Bethpage, New York and at St Augustine in Florida.

The first production A-10A was delivered to Davis-Monthan Air Force Base, Ariz., in October 1975. It was designed especially for the close air support mission and had the ability to combine large military loads, long loiter and wide combat radius, which proved to be vital assets to America and its allies during Operation Desert Storm. In the Gulf War, A-10s, with a mission capable rate of 95.7 percent, flew 8,100 sorties and launched 90 percent of the AGM-65 Maverick missiles. The Thunderbolt II has also participated in operations Southern Watch, Provide Comfort, Desert Fox, Noble Anvil, Deny Flight, Deliberate Guard, Allied Force, Enduring Freedom and Iraqi Freedom.

The upgraded A-10C reached initial operation capability in September 2007. Specifically designed for close air support, its combination of large and varied ordnance load, long loiter time, accurate weapons delivery, austere field capability, and survivability has proven invaluable to the United States and its allies.Over 350 A-10 aircraft are in service with the US Air Force, Air Combat Command, the US Air Force Reserve and the Air National Guard.

Boeing (McDonnell Douglas) F/A-18 Hornet and Super Hornet

Boeing F/A-18 Hornet
The F/A-18 “Hornet” is a single- and two-seat, twin engine, multi-mission fighter/attack aircraft that can operate from either aircraft carriers or land bases. The F/A-18 fills a variety of roles: air superiority, fighter escort, suppression of enemy air defenses, reconnaissance, forward air control, close and deep air support, and day and night strike missions. The F/A-18 Hornet replaced the F-4 Phantom II fighter and A-7 Corsair II light attack jet, and also replaced the A-6 Intruder as these aircraft were retired during the 1990s.

The F/A-18 has a digital control-by-wire flight control system which provides excellent handling qualities, and allows pilots to learn to fly the airplane with relative ease. At the same time, this system provides exceptional maneuverability and allows the pilot to concentrate on operating the weapons system. A solid thrust-to-weight ratio and superior turn characteristics combined with energy sustainability, enable the F/A-18 to hold its own against any adversary. The power to maintain evasive action is what many pilots consider the Hornet’s finest trait. In addition, the F/A-18 was also the Navy’s first tactical jet aircraft to incorporate a digital, MUX bus architecture for the entire system’s avionics suite. The benefit of this design feature is that the F/A-18 has been relatively easy to upgrade on a regular, affordable basis.

Making the first flight in November 1978, the F/A-18 and its two-place derivative [subsequently redesignated the F/A-18B] underwent most of their development testing at the Naval Air Test Center under the new single-site testing concept. While much attention was focused on development problems, these were largely typical of those in any new program, with their resolution being part of the development process. For the most part, these occurred in the basic aircraft hardware rather than in the digital electronic systems.

The original F/A-18A (single seat) and F/A-18B (dual seat) became operational in 1983 replacing Navy and Marine Corps F-4s and A-7s. It quickly became the battle group commander’s mainstay because of its capability, versatility and availability. Reliability and ease of maintenance were emphasized in its design, and F/A-18s have consistently flown three times more hours without failure than other Navy tactical aircraft, while requiring half the maintenance time.

The Hornet has been battle tested and has proved itself to be exactly what its designers intended: a highly reliable and versatile strike fighter. The F/A-18 played an important role in the 1986 strikes against Libya. Flying from USS CORAL SEA (CV 43), F/A-18s launched high-speed anti-radiation missiles (HARMs) against Libyan air defense radars and missile sites, effectively silencing them during the attacks on Benghazi facilities.

Following a successful run of more than 400 A and B models, the US Navy began taking fleet deliveries of improved F/A-18C (single seat) and F/A-18D (dual seat) models in September 1987. These Hornets carry the Advanced Medium Range Air-to-Air Missile (AMRAAM) and the infrared imaging Maverick air-to-ground missile. Two years later, the C/D models came with improved night attack capabilities. The new components included a navigation forward looking infrared (NAVFLIR) pod, a raster head-up display, night vision goggles, special cockpit lighting compatible with the night vision devices, a digital color moving map and an independent multipurpose color display.

F/A-18Cs have synthetic aperture ground mapping radar with a Doppler beam sharpening mode to generate ground maps. This ground mapping capability that permits crews to locate and attack targets in adverse weather and poor visibility or to precisely update the aircraft’s location relative to targets during the approach, a capability that improves bombing accuracy. New production F/A-18Cs received the APG-73 radar upgrade radars starting in 1994, providing more precise and clear radar displays.

The F/A-18C Nigh Attack Hornet has a pod-mounted Hughes AN/AAR-50 thermal imaging navigation set, a Loral AN/AAS-38 Nite Hawk FLIR targeting pod, and GEC Cat’s Eyes pilot’s night vision goggles. Some 48 F/A-18D two-seat Hornets are configured as the F/A-18D (RC) reconnaissance version, with the M61A1 cannon replaced by a pallet-mounted electro-optical suite comprising a blister-mounted IR linescan and two roll-stabilized sensor units, with all of these units recording onto video tape.

On the first day of Operation Desert Storm, two F/A-18s, each carrying four 2,000 lb. bombs, shot down two Iraqi MiGs and then proceeded to deliver their bombs on target. Throughout the Gulf War, squadrons of U.S. Navy, Marine and Canadian F/A-18s operated around the clock, setting records daily in reliability, survivability and ton-miles of ordnance delivered.

The multi-mission F/A-18E/F “Super Hornet” strike fighter is an upgrade of the combat-proven night strike F/A-18C/D. The Super Hornet will provide the battle group commander with a platform that has range, endurance, and ordnance carriage capabilities comparable to the A-6 which have been retired. The F/A-18E/F aircraft are 4.2 feet longer than earlier Hornets, have a 25% larger wing area, and carry 33% more internal fuel which will effectively increase mission range by 41% and endurance by 50%. The Super Hornet also incorporates two additional weapon stations. This allows for increased payload flexibility by mixing and matching air-to-air and/or air-to-ground ordnance. The aircraft can also carry the complete complement of “smart” weapons, including the newest joint weapons such as JDAM and JSOW.

The Super Hornet can carry approximately 17,750 pounds (8,032 kg) of external load on eleven stations. It has an all-weather air-to-air radar and a control system for accurate delivery of conventional or guided weapons. There are two wing tip stations, four inboard wing stations for fuel tanks or air-to-ground weapons, two nacelle fuselage stations for Sparrows or sensor pods, and one centerline station for fuel or air-to-ground weapons. An internal 20 mm M61A1 Vulcan cannon is mounted in the nose.

Carrier recovery payload is increased to 9,000 pounds, and its engine thrust from 36,000 pounds to 44,000 pounds utilizing two General Electric F414 turbo-fan engines. Although the more recent F/A-18C/D aircraft have incorporated a modicum of low observables technology, the F/A-18E/F was designed from the outset to optimize this and other survivability enhancements.

The Hughes Advanced Targeting Forward-Looking Infra-Red (ATFLIR), the baseline infrared system for the F/A-18 E/F, will also be deployed on earlier model F/A-18s. The Hughes pod features both navigation and infrared targeting systems, incorporating third generation mid-wave infrared (MWIR) staring focal plane technology.

The aircraft made its debut at Patuxent River (Md.) Naval Air Station in September 1995. The F/A18-E/F has achieved many milestones since its debut. The most significant was initial sea trials aboard USS John C. Stennis (CVN 74), the Navy’s newest aircraft carrier. These first Super Hornet carrier qualifications occurred in January 1997 off the coast of Florida, and consisted of a series of tests including catapult launches, arrested landings and various other system evaluations conducted by flight deck crews.

The Super Hornet is fully capable to conduct both air-to-air and air-to-ground combat missions. This includes air superiority, day/night strike with precision-guided weapons, fighter-escort, close air support, suppression of enemy air defenses, reconnaissance, forward air control and refueling. The Super Hornet has greater range/endurance, can carry a heavier payload, has enhanced survivability, and a built-in potential to incorporate future systems and technologies.

McDonnell Douglas F-4 Phantom II

The McDonnell two-place, twin jet, all-weather F-4 Phantom II, with top speeds more than twice that of the speed of sound, was one of the most versatile fighters ever built. A fast and powerful aircraft that proved itself in roles such as interceptor, air-superiority fighter, attack aircraft, and reconnaissance platform. The F-4 was built in large quantities, had a significant combat history, and still remains in service with a number of foreign air arms, over 40 years after its introduction.

The F-4 was put into service by the Air Force and Navy serving a variety of roles in the Vietnam conflict. The final application of the F-4 by the U.S. was in the “Wild Weasel” role for suppressing enemy air defense systems. F-4 production ended in 1979 after over 5,000 had been built-more than 2,600 for the U.S. Air Force, about 1,200 for the U.S. Navy and U.S. Marine Corps, and the rest for friendly foreign nations. Later versions of the aircraft were in the U.S. Air Force inventory until December 1995.

Under its own financing and initiative, McDonnell Aircraft began developing an all-weather attack fighter in August 1953, shortly after it lost a competitive bid to build a Navy supersonic air-superiority fighter. McDonnell had already produced more than 1,000 carrier-based jet aircraft, the FH-1 Phantom, the F2H Banshee and the F3H Demon.

In 1954, the Navy selected McDonnell Aircraft to begin production of the fighter, designated the F4H, which was to be a fleet defense fighter that could take off from an aircraft carrier, have a cruise distance of 250 mi, intercept intruders, and then return to the carrier 3 hr after takeoff. The aircraft was to be armed with missiles and would not carry guns. It would operate as a high-speed (Mach number of 2), standoff missile launcher that would not engage in close-in combat. . Just 31 months after its first flight, the F-4 was the U.S. Navy’s fastest, highest-flying and longest-range fighter. It first flew May 27, 1958, and entered service in 1961. It was named Phantom II on July 3, 1959, during a ceremony held at the McDonnell plant in St. Louis, Mo., to celebrate the company’s 20th anniversary.

During the first few years of the Vietnam conflict, the U.S. found itself engaging enemy aircraft such as the MiG-17 and MiG-19 that were relatively agile and could easily outmaneuver the heavier U.S. aircraft (F-4 and F-105) that had been designed without requirements for close dogfighting or close weapons such as a gun. Initial tactics used by U.S. pilots to try and turn with enemy aircraft had been relatively unsuccessful, and it had become apparent that missiles in use at that time were relatively unreliable at long ranges. Pilot training and revised tactics were ultimately employed to blunt the threat and use U.S. aircraft to an advantage, but the lack of maneuverability and a gun for close-in combat became issues for the Air Force. A new Air Force version known as the F-4E was equipped with a nose mounted M61 cannon, and additional deliveries to the Air Force began in October 1967.

Both U.S. military flight demonstration teams, the Navy Blue Angels and the Air Force Thunderbirds, flew the Phantom II from 1969 to 1973.  The 5,000th Phantom was delivered on May 24, 1978, in ceremonies that also marked the 20th anniversary of the fighter’s first flight, and McDonnell Douglas delivered the last St. Louis-built Phantom II in October 1979.

By 1998, approximately 800 were still in service around the world. With the upgrades already performed and those under contract, the F-4 Phantom II will probably still be flying in 2015 — nearly 60 years after its first flight.

The Navy fighter garnered a host of world speed and time-to-climb records. On 06 December 1959 Commander L.E. Flint, piloting a McDonnell F4H-1 Phantom II powered by two GE J-79 engines bettered the existing world altitude record by reaching 98,560 feet over Edwards Air Force Base.
