The Henschel Hs 117 "Schmetterling" (German for "Butterfly") was a radio-guided German surface-to-air missile project developed during World War II.
 There was also an air-to-air version, the Hs 117H.
Aerial warfare is the battlespace use of military aircraft and other flying machines in warfare.
 Aerial warfare includes bombers attacking enemy installations or a concentration of enemy troops or strategic targets; fighter aircraft battling for control of airspace; attack aircraft engaging in close air support against ground targets; naval aviation flying against sea and nearby land targets; gliders, helicopters and other aircraft to carry airborne forces such as paratroopers; aerial refueling tankers to extend operation time or range; and military transport aircraft to move cargo and personnel.
 Historically, military aircraft have included lighter-than-air balloons carrying artillery observers; lighter-than-air airships for bombing cities; various sorts of reconnaissance, surveillance and early warning aircraft carrying observers, cameras and radar equipment; torpedo bombers to attack enemy shipping; and military air-sea rescue aircraft for saving downed airmen.
 Modern aerial warfare includes missiles and unmanned aerial vehicles. Surface forces are likely to respond to enemy air activity with anti-aircraft warfare.
The Henschel Hs 294 was a guided air-to-sea missile developed by Germany during World War II, in 1943.
 It was a further development of the Henschel Hs 293, but was of an elongated, more streamlined shape.
 When launched from an aircraft, it was guided to its target with the same "Kehl-Straßburg" remote control system as both the Hs 293 and unpowered Fritz X armored PGM systems used for their MCLOS guidance needs.
 Just before it reached its target, it was guided into the water, whereupon its wings would break off, then it then would run like a torpedo, propelled by its remaining kinetic energy; it would explode below the water line of the vessel.
 The proximity fuze was that of a regular German torpedo.
The Henschel Hs 122 was a German army cooperation/reconnaissance aircraft of the mid-1930s, radial-engined and with a parasol wing.
 Though only pre-production variants entered service, the Hs 122 led on to the Hs 126 which was produced in large numbers.
The Henschel Hs 126 was a German two-seat reconnaissance and observation aircraft of World War II that was derived from the Henschel Hs 122.
 The pilot was seated in a protected cockpit under the parasol wing and the gunner in an open rear cockpit.
 The prototype aircraft frame was that of a Hs 122A fitted with a Junkers engine.
 The Hs 126 was well received for its good short takeoff and low-speed characteristics which were needed at the time.
 It was put into service for a few years, but was soon superseded by the general-purpose, STOL Fieseler Fi 156 "Storch" and the medium-range Focke-Wulf Fw 189 "flying eye".
The Henschel Hs 125 was a German advanced training aircraft prototype featuring a single engine and low wing, designed by Henschel & Son and tested by the Luftwaffe during World War II.
 Only two prototypes were ever built.
The Henschel Hs 121 was the first aircraft built by the German Henschel company.
 It was a high-wing monoplane with an inline engine, fixed undercarriage and single, open cockpit, designed as an advanced trainer.
 Only one aircraft was produced, in 1933-4, as a testpiece for the Air Ministry.
The Luftwaffe (] ) was the aerial warfare branch of the combined German Wehrmacht military forces during World War II.
 Germany's military air arms during World War I, the "Luftstreitkräfte" of the Army and the "Marine-Fliegerabteilung" of the Navy, had been disbanded in May 1920 as a result of the terms of the Treaty of Versailles which stated that Germany was forbidden to have any air force.
The Henschel Hs 298 was a 1940s German rocket-powered air-to-air missile designed by Professor Herbert Wagner of Henschel.
Henschel's Hs 132 was a World War II dive bomber and interceptor aircraft of the German "Luftwaffe" that never saw service.
 The unorthodox design featured a top-mounted BMW 003 jet engine (identical in terms of make and position to the powerplant used by the Heinkel He 162) and the pilot in a prone position.
 The Soviet Army occupied the factory just as the Hs 132 V1 was nearing flight testing, the V2 and V3 being 80% and 75% completed.
