The B-2 Spirit, a key component of the United States’ stealth bomber fleet, owes much of its radar evasion capabilities to its four General Electric F118-GE-100 non-afterburning turbofan engines. These engines were developed from the F110 engines used in F-16 and F-15 fighter aircraft but have been adapted for the B-2’s stealth requirements.
The U-2S reconnaissance aircraft also utilizes these reliable engines. While details about the B-2 program remain classified, it is known that these engines play a significant role in the aircraft’s performance.
An iconic symbol of American air power, the B-2 originated from a need during the 1970s to evade Soviet radar systems. The Advanced Technology Bomber Program led to Northrop Corporation being awarded a contract in 1979 to develop this next-generation bomber. After years of development, the B-2 was publicly revealed in 1988 as a strategic bomber with advanced radar-evasion capabilities.
The first prototype, “Spirit of America,” took flight in 1989, and by 1993, the B-2 entered service with the United States Air Force. Powered by four General Electric F118-GE-100 engines, it can fly intercontinental missions undetected and carry both conventional and nuclear payloads.
The design innovations include specially shaped intakes and exhaust nozzles that contribute to its stealth capabilities. With an unrefueled range of approximately 6,000 nautical miles and mid-air refueling capability extending its range indefinitely, it can conduct global strike missions from its base in Missouri without landing.
In recent developments, lessons learned from the B-2 have influenced the design of its successor, the B-21 “Raider.” Although using more advanced propulsion systems than those found on the B-2 Spirit, these advancements are built upon knowledge gained from operating GE F118 engines.
