It will sound like a C751B.
Was expecting Mitsubishi to get the propulsion system contract,
but this is kind of a pleasant surprise.
Because the company that supplies the propulsion system for
C151A is the same company that supplies the propulsion system
for C751B.
Also, considering that most of the technologies
implemented in C151A are a derivative of C751B, one can
pretty much conclude quite a number of things.
