The KJB-4 is a four engine supersonic strategic bomber.In 1956,the Kosyuu Air Force issued requirements for a new bomber combining the payload of the previous generation bombers and the capability of reaching Mach 2. The new bomber was expected to enter service in 1964. Kinjyo Heavy Industries (KHI)was chosen to design and manufacture the new bomber.But despite the effort made by the designers at KHI, they could not make the sleek body with a internal bomb bay needed for supersonic flight. 1958 the Air Force imported a number of Dominator MK-IIIs from Pilotmario to study its design.The fuselage and the bomb bay design of the Dominator was so impressive that KHI decided to use its design on the new supersonic bomber. KHI simply redesigned the nose of the Dominator and gave it a sharp nose for supersonic flight.The wings of the new bomber had a combination of a delta wing with a canard. This wing design was already proven to be stable on supersonic flights with the KJ-2 fighter. The new bomber was fitted with newly designed J-36 engines . The first flight of the new KJB-4 took place in 1962 and entered service in1964.
Press 7 and vtol up to open bomb bay.
Press1-5 to deploy bombs.

Take off with 18% of thrust . In leveled flight fly with 30-50% of thrust. You can fly with 100% thrust and fly over 2000mph but the fuel consumption rate will be high.
Warning : Do not bomb when flying over 1300mph. You will blow yourself up.
