The Douglas AIR-2 Genie (previous designation MB-1) was an unguided air-to-air rocket with a 1.5 kt W25 nuclear warhead. [1] It was deployed by the United States Air Force (USAF 1957–1985) and Canada (Royal Canadian Air Force 1965–1968, Air Command 1968–1984) [2] during the Cold War.
RS-68 being tested at NASA's Stennis Space Center Viking 5C rocket engine used on Ariane 1 through Ariane 4. A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket.

The BE-4 (Blue Engine 4) [5] is an oxygen-rich, [6] liquefied-methane-fueled, staged-combustion, rocket engine. It is produced by Blue Origin. BE-4 was developed with private and public funding. [7] The engine produces 2,400 kilonewtons (550,000 lbf) of thrust at sea level. [8]
In late 2001, Mueller began developing a liquid-fueled rocket engine in his garage and later moved his project to a friend's warehouse in 2002. [1] His design was the largest amateur liquid-fuel rocket engine, weighing 80 lb (36 kg) and producing 13,000 lbf (58 kN) of thrust. [1] His work caught the attention of Elon Musk, SpaceX founder.

The company is headquartered on 11 hectares (26 acres) of industrial land in Kent, Washington, a suburb of Seattle, where its research and development is located.The facility was 24,000 m 2 (260,000 sq ft) in size in early 2015, [3] growing to 28,000 m 2 (300,000 sq ft) by March 2016 with Blue Origin leasing additional space in adjacent office buildings.
The XLR11-RM-5 engine was first used in the Bell X-1.On October 14, 1947, the X-1 became the first aircraft to fly faster than the speed of sound (Mach 1). The XLR11-RM-5 was also used in the X-1A and X-1B, and as a booster engine in the U.S. Navy's D-558-2 Douglas Skyrocket turbojet (where it was designated the XLR8-RM-5).
The BE-3 (Blue Engine 3) is a liquid hydrogen/liquid oxygen rocket engine developed by Blue Origin. The engine began development in the early 2010s and completed acceptance testing in early 2015. The engine is being used on the New Shepard suborbital rocket, for which made its first test flight on 29 April 2015 and had its first crewed flight ...
