it was 2033, when the bombs came down. millions of deaths. it was horrible.
as a final attempt to strike back on russia, (no offense) the american goverment decided to launch project 74.
in 23 days they designed this cheap to build, very powerful and relyable nuclear bomber. mass produced in june 2034, they flew under heavy protection by heavy fighters to russia, where they destroyed hundreds of cities and killed millions of people.
now, after 17 years, when the word has become a nuclear wasteland with just a few thousend people alive, one of the radars malfunctioned,and noticed thousands of nuclear rockets incoming,
and send out the last bomber on his maiden voyage.

AG1-AG3 for arming the bombs, because if you don't activate and drop them 1 by 1 they will get stuck on other bombs
AG4 for the landing parachute
AG7 for the lights
VTOL for the turret
