By me mid 1940s, gas turbine (turbojet) engine development had advanced to a point where turbojet power plant contractors could boast of lower engine dry weight and spe­cific fuel consumption, higher sea level static thrust rating and engine-thrust-to-weight ratio. These claims created a great deal of optimism, and for the first time, that optimism over­shadowed earlier pessimism. It was with this new belief in progress that the United States Army Air Forces (USAAF) was prompted to sire sever­al new and important turbojet engine-powered fighter aircraft programs. One such program was its revised long-range bomber escort and strike fighter, which it now called the Penetration Fighter program.
