Second Tomcat is referred to as an F-14A+ Kai from the anime Macross Zero.
Yes alternate timeline F-14. The Kai boasts the F-110 engines, AIM-120 capability, D model dual nose sensors, late model gun gas purge, late boat tail, and ECM antennas on the intakes. Lt. Shin Kudo's 501 appears to be painted in a modified TPS of Lt and Dk Ghost Gray.
The only decals are from Hasegawa for a boxing of their 1/72d F-14A kit. Which I would like to upscale.
