new aircraft all have the 15mm on them, they are to match all new aircraft for probably then next 5-8 years hopefully. But for now they will be mass produced to get rid of the old stock except for the old dive bomber as it is still very good but just needs to be updated a bit with a new better engine and the 15mmers. Also these will have replaced almost all aircraft by the end of the end and then have replaced all by mid next year. A=Air service L=land service S=Sea service
