![]() The designers built the F-105 around a well-established powerplant: the Pratt & Whitney J75 afterburning turbojet engine. ![]() Designed to supplant the aging F-86 Sabre fighters then still in service with US and Australian forces, the F-105 was a big step forward for its day. The Republic F-105 Thunderchief made its debut just before full US involvement in the war in Vietnam in 1958. No matter what the mission, the F-4 Phantom II is still an impressive bird. Many of the Vietnam-era F-4s did not carry defensive weapons like machine guns or cannons, but they made up for that with a huge payload of missiles in a variety of models or configurations. ![]() With a combat range of 585 miles, it functioned perfectly in either an interceptor or a strike role. Powered by two General Electric J79 axial compressor turbojets, the F-4’s top speed was a still-impressive Mach 2.23. While retired from US service, a look at the numbers indicates that the F-4 Phantom II was a force to be reckoned with in the skies of Southeast Asia. Originally developed for the United States Navy for carrier duty, the F-4 Phantom II saw a lot of action during the Vietnam War. It functions equally as well as either an interceptor or a fighter-bomber. Add in some advanced and consistently upgraded avionics, and the result is a near-perfect platform for hitting NVA targets wherever they were found.Īnother American aircraft, the McDonnell Douglas F-4 Phantom II is a two-seat, twin-engine, all-weather long-range supersonic jet aircraft. The armament is equally frightening, approximately 70,000 pounds of any variety of ordinance including bombs, mines, missiles, or even nuclear weapons. The net result is a top speed of 650 miles per hour with a maximum range of nearly 9,000 miles without refueling. With a crew of five, the B-52 aircraft gets its power from eight Pratt & Whitney TF33 turbofan engines, each of which produces 17,000 lbf. The result was the Boeing B-52 Stratofortress, a Vietnam War aircraft so powerful and versatile that it remains in service to this day. The US needed a long-range subsonic strategic bomber capable of delivering a huge amount of ordinance, either conventional or nuclear, to an enemy position deep within their airspace. ![]() This American project was first conceived in the immediate wake of the Second World War. ![]()
