B-1B Lancer Technical

After the cold war all B-1 bombers where updated by B-1B Conventional Mission Upgrade which was separated into 4 blocks, from block C till block F. Thanks to this the B-1 can fly lower (to fly beneath enemy radar) and has more advanced electronics.
The B1 has 3 weapon storage's for the bombs. Extra bombs can be carried under the aircraft's wings. The B-1 can be equipped with the most bombs which are use by the USAF military.

The B-1B is equipped with 4 F101-GE-102 turbofan engines with afterburner. Each engine provides more than 30.000 lbs thrust. The F101 engine was originally developed during the development of a new aircraft with the project name: Advanced Manned Strategic Aircraft program
. The F101-GE-101 engines was introduced by General Electric in 1970. After test flights with 4 B-1B's, the General Electric has developed a improved version; the F101-GE-102. There have been delivered 469 of these engines between 1983 and 1986 to the USAF.

The engines are mounted beneath the wing roots, near the main gears. There are 2 separate air inlet ducts on both sides.
