As a design engineer, Gowadia was reportedly one of the principal designers of the B-2 Spirit stealth bomber, [citation needed] who conceived and conceptually designed the B-2 bomber's entire propulsion system and billed himself as the "father of the technology that protects the B-2 stealth bomber from heat-seeking missiles."
The F118 is a non-afterburning derivative of the F110 specially developed for the B-2 Spirit stealth bomber. A single stage HP turbine drives the 9 stage HP compressor, while a 2-stage LP turbine drives the 3 stage fan. The combustor is annular. In 1998, the USAF's Lockheed U-2S fleet was fitted with a modified version of the F118. [1]
Hal Markarian (1929 — 2012) was an Armenian American aircraft designer who is known for implementing the initial designs of the B-2 Stealth Bomber. He produced a sketch that was the inspiration for the modern B-2 Spirit. [1] Today's B-2 Spirit incorporates much of Markarian's design.
It is intended that the bomb will be deployed on the B-2 Spirit, and will be guided using GPS. [6] [7] It is also planned to be deployed on the B-21 Raider. [8] In July 2007, Northrop Grumman announced a $2.5-million stealth-bomber refit contract. Each of the U.S. Air Force's B-2s is to be able to carry two 14-ton MOPs. [9] [10]
The AN/APQ-181 is an all-weather, low probability of intercept (LPI) phased array radar system designed by Hughes Aircraft (now Raytheon) for the U.S. Air Force B-2A Spirit bomber aircraft. The system was developed in the mid-1980s and entered service in 1993.
On 23 February 2008, a B‑2 crashed on the runway shortly after takeoff from Andersen Air Force Base in Guam. [1] The crash of the Spirit of Kansas, 89-0127, which had been operated by the 393rd Bomb Squadron, 509th Bomb Wing, Whiteman Air Force Base, Missouri, and had logged 5,100 flight hours, [6] was the first crash of a B‑2.

The 393rd Bomb Squadron was activated as a Boeing B-29 Superfortress squadron in early 1944; trained under the Second Air Force.Due to a shortage of B-29s, the squadron was initially equipped with former II Bomber Command Boeing B-17 Flying Fortresses previously used for training heavy bomber replacement personnel as engineering flaws were being worked out of the B-29.
