This is a prototype scheme of the F/A-18 Super Hornet, E4. Not much else but the skin is What You See Is What You Get as the original files for this aircraft were lost, so I'm just getting unused skins that are complete out to the public. Simply drop this in your FA-18E_BlkI folder and go fly. Can be found under the drop down menu as "E4 Prototype"

This was an F/A-18B aasigned to NSAwC and used as an adversary aircraft. Drop it in your FA-18B folder and go fly. It can be found under NSAWC "Topgun" in the selection menu.

I'm not sure if it was an F/A-18B or D that this skin goes on, but in either case drop this in the appropriate folder and go fly. In the drop down menu it is under VFA-125 Desert

This skin is a "best fit" skin to the Hornet Team F/A-18D. To install the skin simply drop in the FA-18D folder and go fly. It can be found under VMFA(AW)-225 in the dropdown menu.

This is the F/A-18C version of VFA-94 on its 2005 cruise. The FA-18 series by the Hornet Team is required for this skin, and drop this skin in the FA-18C_03 directory and go fly. The VFA-195 decals are required (should be part of the pack already) for the correct modex for the aircraft.

This skin represents the line jets of VFA-94 in May 2019. All necessary files are included, and the folder layout is just as it needs to be, with all the appropriate directories laid out for installation. In the drop down menu for  the aircraft, select VFA-94 2019 and go fly

This is a skin depicting the CAG jet of VFA-94 in March 2017. 
To use this simply drop in your FA-18F_BlkII folder and go fly, it can be found under VFA-94 CAG March 2017

This is a skin depicting the CAG jet of VFA-136 during I believe 2011 or so. Since I'm going off of a few reference shots (thanks to Svetlin for a handy reference file) it is the best I can manage with what I have, so it should  be close enough.
Simply add to the FA-18E_BlkII folder and go fly. Name on the dropdown menu is VFA-136 CAG 2011
