Question: In what year was the competition held that inspired the design of the only acknowledged aircraft that can carry large air-to-surface standoff weapons in stealth configuration?
Context: The Lockheed Senior Peg was an experimental design by the Lockheed Corporation that competed with a design by Northrop (Senior Ice) for a stealth aircraft which would eventually become the Northrop Grumman B-2 Spirit.  It was created as part of the Advanced Technology Bomber competition, The competition started in 1979. The World Championship of Custom Bike Building is a competition held annually by "American Motorcycle Dealer" (AMD) magazine.  The first competition was held in 2004 as an extension of the AMD ProShow custom engineering competition held in Europe in conjunction with Custom Chrome since 2002, which by some was already unofficially acknowledged as a European championship The top three finishers from the European Championship are rewarded with an entry to the World Championship and an expenses contribution to help with bike freight costs.  There are also a number of affiliate events in various countries in Western Europe as well as in Russia, Japan, Australia and Mexico.  The winner of each Affiliate event also wins expenses towards competing at the World Championship each year.  The judging of the World Championship is done by 'peer review', in that all competitors collectively decide the winner, together with a select panel of invited judges from the press and aftermaket industry. The AN/AAQ-28(V) LITENING targeting pod is an Israeli-designed precision targeting pod system currently operational with a wide variety of combat aircraft.  LITENING significantly increases the combat effectiveness of the aircraft during day, night and under-the-weather conditions in the attack of ground and air targets with a variety of standoff weapons (i.e., laser-guided bombs, conventional bombs and GPS-guided weapons).  The thousandth pod was sold in October 2010. The Northrop (later Northrop Grumman) B-2 Spirit, also known as the Stealth Bomber, is an American heavy penetration strategic bomber, featuring low observable stealth technology designed for penetrating dense anti-aircraft defenses; it is a flying wing design with a crew of two.  The bomber can deploy both conventional and thermonuclear weapons, such as eighty 500 lb -class (Mk 82) JDAM Global Positioning System-guided bombs, or sixteen 2400 lb B83 nuclear bombs.  The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. A submarine-launched cruise missile (SLCM) is a cruise missile that is launched from a submarine (especially a SSG or SSGN).  Current versions are typically standoff weapons known as land-attack cruise missiles (LACMs), which are used to attack predetermined land targets with conventional or nuclear payloads.  Anti-ship cruise missiles (ASCMs) are also used, and some submarine-launched cruise missiles have variants for both functions. The Air Armament Center (AAC) was an Air Force Material Command (AFMC) center at Eglin Air Force Base, Florida, responsible for development, acquisition, testing, and deployment of all air-delivered weapons for the U.S. Air Force.  Weapon systems maintained by the center included the Advanced Medium Range Air-to-Air Missile, High-speed anti-radiation missile, HARM Targeting System, Joint Air-to-Surface Standoff Missile, Joint Direct Attack Munition, Miniature Air-Launched Decoy, Sensor Fuzed Weapon, and the Small Diameter Bomb. An air-launched cruise missile (ALCM) is a cruise missile that is launched from a military aircraft.  Current versions are typically standoff weapons which are used to attack predetermined land targets with conventional, nuclear or thermonuclear payloads. The Bombardment Aircraft Rocket, also known as BOAR, the Bureau of Ordnance Aircraft Rocket, and officially as the 30.5-Inch Rocket, Mark 1, Mod 0, was an unguided air-to-surface rocket developed by the United States Navy's Naval Ordnance Test Station during the 1950s.  Intended to provide a standoff nuclear capability for carrier-based aircraft, the rocket entered operational service in 1956, remaining in service until 1963. The AGM-158 JASSM (Joint Air-to-Surface Standoff Missile) is a low observable standoff air-launched cruise missile developed in the United States.  It is a large, stealthy long-range weapon of the 2,000 pounds (910 kg) class.  The missile's development began in 1995, but a number of problems during testing delayed its introduction into service until 2009.  As of 2014, the JASSM has entered foreign service in Australia, Finland, and Poland.  An extended range version of the missile, the AGM-158B JASSM-ER (Joint Air-to-Surface Standoff Missile-Extended Range), entered service in 2014. The Kh-29 (Russian: Х-29 ; NATO: AS-14 'Kedge' ; GRAU: 9M721) is a Soviet air-to-surface missile with a range of 10–30 km.  It has a large warhead of 320 kg, has a choice of laser, infrared, active radar or TV guidance, and is typically carried by tactical aircraft such as the Su-24, Su-30, MiG-29K as well as the "T/TM" models of the Su-25, giving that craft an expanded standoff capability.
