The American Aircraft Penetrator was modified from a helicopter produced by what nation's military?
Bell UH-1 Iroquois The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter powered by a single turboshaft engine, with two-blade main and tail rotors. The first member of the prolific Huey family, it was developed by Bell Helicopter to meet a United States Army's 1952 requirement for a medical evacuation and utility helicopter, and first flew in 1956. The UH-1 was the first turbine-powered helicopter to enter production in 1960 for the United States military, and more than 16,000 have been built since.
Sikorsky CH-148 Cyclone The Sikorsky CH-148 Cyclone is a twin-engine, multi-role shipboard helicopter being developed by the Sikorsky Aircraft Corporation for the Canadian Forces. A military variant of the Sikorsky S-92, the CH-148 is designed for shipboard operations and is intended to replace the venerable CH-124 Sea King, which has been in operation since 1963. The search for a Sea King replacement originally began in the 1980s.
