The engine's 150:1 thrust-to-weight ratio is the highest ever achieved for a rocket engine. [ 8 ] [ 9 ] The first flight of the Merlin 1D engine was also the maiden Falcon 9 v1.1 flight. [ 10 ]
There are several standards for determining the weight of an aircraft used to calculate the thrust-to-weight ratio range. ... SpaceX Raptor 3 rocket engine [30] 1,525 ...
When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [16] and a height of 121.3 m (398 ft). [17] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [18] it consists of the Super Heavy booster and the Starship upper stage [19] which are powered by Raptor and Raptor Vacuum engines.

The Raptor engine uses a full-flow staged combustion cycle with oxygen and methane-rich turbopumps. [27] [28] Before 2014, only two full-flow staged-combustion rocket engine designs had advanced enough to undergo testing: the Soviet RD-270 project in the 1960s and the Aerojet Rocketdyne Integrated Powerhead Demonstrator in the mid-2000s.

In October 2012, SpaceX publicly announced concept work on a rocket engine that would be "several times as powerful as the Merlin 1 series of engines, and won't use Merlin's RP-1 fuel". [58] They indicated that the large engine was intended for a new SpaceX rocket, using multiple of these large engines could notionally launch payload masses of ...
On 8 September 2005, SpaceX announced the development of the Falcon 9 rocket, which has nine Merlin engines in its first stage. [21] The design is an EELV-class vehicle, intended to compete with the Delta IV and the Atlas V, along with launchers of other nations as well. Both stages were designed for reuse.
