This is Cookiemonste's magnificent VFA-146 Splinter Camouflage kindly modified by him to incorporate my personal fictitious squadron, VFA-15 Spartans logos and colouring.
I've added my squadron's helmet art as well.
Cookiemonste's post can be found here: https://www.digitalcombatsimulator.com/en/files/3314557/
There are two versions of these VFA-15 Spartans liveries:
One is just the Spartan helm art on the tail as well as the squadron number inside the tail and on the fuselage. This is VFA-15 Spartans Splinter Gray.
The other has the completely crimson vertical stabilisers as well as helm and squadron number. That one's VFA-15 Spartans Splinter Gray Crimson Tail.
Thanks again, Cookiemonste - an awesome skin!
