|---|---|---|
| OA-27C | Aryx_OA27_C |
Both factions. RCS 0, STOL / low-alt G, 2× turbine, 1 kt suicide fuze. First eject punches the WSO decoy; you cannot bail. |
| OA-27D | Aryx_OA27_D |
BDF only. Extra armor and fuel, 2× turbine, no suicide kit. Second eject is a real bail-out. |
| OA-27E | Aryx_OA27_E |
PALA only. 3× turbine, standing ECM, ground autocannons cannot damage it. Second eject is a real bail-out. |
Unknown HQ keeps both D and E listed. Rank 1.
OA WSO (C/D/E while the rear seater is aboard): dumps inbound missiles inside 10 km; Y/N for flares and target lock (does not steal your selected countermeasure); extra gunsight lead; GLOC floor.
