The Draco Pistol, or more commonly known as simply a Draco, named after the Dacian dragon-like battle banner, [1] [circular reference] is a series of Romanian-designed gas-operated semi-automatic pistols sold by Century International Arms. The weapon is chambered for the 7.62×39mm cartridge with its design taken heavily after the AK-47.
In April 2021, DARPA announced the start of DRACO by awarding 18-month Phase 1 contracts to General Atomics for the nuclear reactor concept design ($22 million), and to Blue Origin ($2.5 million) and Lockheed Martin ($2.9 million) for their competing operation system and demonstration system concept designs.

On February 1, 2012 SpaceX announced that it had completed the development of a new, more powerful storable-propellant rocket engine, this one called SuperDraco. This high-thrust hypergolic engine—about 200 times larger than the Draco RCS thruster hypergolic engine—offers deep throttling ability and just like the Draco thruster, has multiple restart capability and uses the same shared ...
Channels etched into the Merlin 1D nozzle enable regenerative cooling preventing exhaust heat from melting it.. Since the founding of SpaceX in 2002, the company has developed four families of rocket engines — Merlin, Kestrel, Draco and SuperDraco — and since 2016 developed the Raptor methane rocket engine and after 2020, a line of methalox thrusters.
SuperDraco is a hypergolic propellant rocket engine designed and built by SpaceX.It is part of the SpaceX Draco family of rocket engines. A redundant array of eight SuperDraco engines provides fault-tolerant propulsion for use as a launch escape system for the SpaceX Dragon 2, a passenger-carrying space capsule.
DRACO was based on the Long Range Reconnaissance Imager (LORRI) onboard New Horizons spacecraft, and supported autonomous navigation to impact the asteroid's moon at its center. The optical part of DRACO was a Ritchey-Chrétien telescope with a field of view of 0.29° and a focal length of 2.6208 m (f/12.60). The spatial resolution of the ...
