During its combat service, the SBD proved to be an excellent naval scout plane and dive bomber. It possessed long range, good handling characteristics, maneuverability, potent bomb load, great diving characteristics from the perforated dive brakes, good defensive armament, and ruggedness. One land-based variant of the SBD – in omitting the arrestor hook — was purpose-built for the U.S. Army Air Forces, as the A-24 Banshee.
The Hampden served in the early stages of the WW2, bearing the brunt of the early bombing war over Europe, taking part in the first night raid on Berlin and the first 1,000-bomber raid on Cologne. When it became obsolete, after a period of mainly operating at night, it was retired from RAF Bomber Command service in late 1942. By 1943, the rest of the trio were being superseded by the larger four-engined heavy bombers such as the Avro Lancaster.
The aircraft was easily recognisable by its inverted gull wings and fixed spattedundercarriage. Upon the leading edges of its faired main gear legs were mounted the Jericho-Trompete (Jericho trumpet) wailing sirens, becoming the propaganda symbol of German air power and the so-called blitzkrieg victories of 1939–1942. The Stuka's design included several innovations, including automatic pull-up dive brakes under both wings to ensure that the aircraft recovered from its attack dive even if the pilot blacked out from the high g-forces.
The Stuka operated with considerable success in close air support and anti-shipping at the outbreak of World War II. It led air assaults in the invasion of Poland in September 1939. Stukas were critical to the rapid conquest of Norway, the Netherlands, Belgium and France in 1940. Sturdy, accurate, and very effective against ground targets, the Stuka was, like many other dive bombers of the period, vulnerable to fighter aircraft. During the Battle of Britain its lack of manoeuvrability, speed and defensive armament meant that it required a heavy fighter escort to operate effectively.
After the Battle of Britain the Stuka was used in the Balkans Campaign, the African and Mediterranean theatres and the early stages of the Eastern Front where it was used for general ground support, as an effective specialised anti-tank aircraft and in an anti-shipping role. Once the Luftwaffe lost air superiority, the Stuka became an easy target for enemy fighter aircraft on all fronts. It was produced until 1944 for lack of a better replacement. By then ground-attack versions of the Focke-Wulf Fw 190 had largely replaced the Stuka, but Stukas remained in service until the end of the war.
OberstHans-Ulrich Rudel was the most successful Stuka ace and the most highly decorated German serviceman of the Second World War.
An estimated 6,500 Ju 87s of all versions were built between 1936 and August 1944.
The Lockheed AC-130 gunship is a heavily armed, long-endurance, ground-attack variant of the C-130 Hercules transport, fixed-wing aircraft. It carries a wide array of ground attack weapons that are integrated with sophisticated sensors, navigation, and fire-control systems. Unlike other modern military fixed-wing aircraft, the AC-130 relies on visual targeting. Because its large profile and low operating altitudes of approximately 7,000 feet (2,100 m) make it an easy target, its close air support missions are usually flown at night.
The airframe is manufactured by Lockheed Martin, while Boeing is responsible for the conversion into a gunship and for aircraft support. Developed during the Vietnam War as "Project Gunship II", the AC-130 replaced the Douglas AC-47 Spooky, or "Gunship I". The sole operator is the United States Air Force, which uses the AC-130U Spooky and AC-130W Stinger II variants for close air support, air interdiction, and force protection, with the upgraded AC-130J Ghostrider entering service. Close-air-support roles include supporting ground troops, escorting convoys, and urban operations. Air-interdiction missions are conducted against planned targets and targets of opportunity. Force-protection missions include defending air bases and other facilities. AC-130Us are based at Hurlburt Field, Florida, while AC-130Ws are based at Cannon AFB, New Mexico; gunships can be deployed worldwide. The squadrons are part of the Air Force Special Operations Command (AFSOC), a component of the United States Special Operations Command (SOCOM).
The AC-130 has an unpressurized cabin, with the weaponry mounted to fire from the port side of the fuselage. During an attack, the gunship performs a pylon turn, flying in a large circle around the target, therefore being able to fire at it for far longer than in a conventional strafing attack. The AC-130H Spectre was armed with two 20 mm M61 Vulcan cannons, one L60 Bofors 40 mm cannon, and M137 105 mm cannon and M37 recoil mechanism from the M102 howitzer; after 1994, the 20 mm cannons were removed. The upgraded AC-130U Spooky has a single 25 mm GAU-12 Equalizer cannon in place of the Spectre's two 20 mm cannons, an improved fire-control system, and increased ammunition capacity. The new AC-130J was based on the MC-130J Commando II special-operations tanker. The AC-130W Stinger II is a modified C-130H with upgrades including a precision strike package.
The B-1 was first envisioned in the 1960s as a platform that would combine the Mach 2 speed of the B-58 Hustler with the range and payload of the B-52, and was meant to ultimately replace both bombers. After a long series of studies, Rockwell International (now part of Boeing) won the design contest for what emerged as the B-1A. This version had a top speed of Mach 2.2 at high altitude and the capability of flying for long distances at Mach 0.85 at very low altitudes. The combination of the high cost of the aircraft, the introduction of the AGM-86cruise missile that flew the same basic profile, and early work on the stealth bomber all significantly affected the need for the B-1. This led to the program being canceled in 1977, after the B-1A prototypes had been built.
The program was restarted in 1981, largely as an interim measure due to delays in the B-2 stealth bomber program. This led to a redesign as the B-1B, which differed from the B-1A by having a lower top speed of Mach 1.25 at high altitude, but improved the low-altitude speed to Mach 0.96. The electronics were also extensively improved, and the airframe was improved to allow takeoff with the maximum possible fuel and weapons load. Deliveries of the B-1B began in 1986 and formally entered service with Strategic Air Command (SAC) as a nuclear bomber that same year. By 1988, all 100 aircraft had been delivered.
In the early 1990s, following the Gulf War and concurrent with the disestablishment of SAC and its reassignment to the newly formed Air Combat Command, the B-1B was converted for a conventional bombing role. It first served in combat during Operation Desert Fox in 1998 and again during the NATO action in Kosovo the following year. The B-1B has supported U.S. and NATO military forces in Afghanistan and Iraq. The Air Force had 62 B-1Bs in service as of 2016. The Northrop Grumman B-21 Raider is to begin replacing the B-1B after 2025; all B-1s are planned to be retired by 2036.
