The Merlin 1B rocket engine was an upgraded version of the Merlin 1A engine. The turbopump upgrades were handled by Barber-Nichols, Inc. for SpaceX. [ 10 ] It was intended for Falcon 1 launch vehicles, capable of producing 380 kN (85,000 lbf) of thrust at sea level and 420 kN (95,000 lbf) in vacuum, and performing with a specific impulse of 261 ...
Merlin 1 is a family of LOX/RP-1 rocket engines developed 2003–2012. Merlin 1A and Merlin 1B utilized an ablatively-cooled carbon-fiber composite nozzle. Merlin 1A produced 340 kilonewtons (76,000 lb f) of thrust and was used to power the first stage of the first two Falcon 1 flights in 2006 and 2007.
The main changes from Block 3 (the original Falcon 9 Full Thrust) to Block 5 are higher-thrust engines and improvements to the landing legs along with numerous other small changes to streamline recovery and re-use of first-stage boosters and increase the production rate. Each Block 5 booster is designed to fly ten times with only minor ...

SpaceX's Merlin and Kestrel rocket engines use a RP-1 and liquid oxygen ("kerolox") combination. Raptor has about triple the thrust of SpaceX's Merlin 1D engine, which powers the Falcon 9 and Falcon Heavy launch vehicles. Raptor was conceived to burn hydrogen and oxygen propellants as of 2009. [36]
The Falcon 9 v1.1 ELV was a 60 percent heavier rocket with 60 percent more thrust than the v1.0 version of the Falcon 9. [15] It includes realigned first-stage engines [16] and 60 percent longer fuel tanks, making it more susceptible to bending during flight. [15] The engines were upgraded from the Merlin 1C to the more powerful Merlin 1D engines.
The BFR would be able to launch 100 t (220,000 lb) to LEO and would be equipped with Merlin 2 engines. The Merlin 2 would have been in direct lineage to the Merlin engines used on the Falcon 9 , described as a scaled up regeneratively cooled engine comparable to the F-1 engines used on the Saturn V .
