Basic maths, navy currently have 8 Gabyas, 6+2 Mekos(4 only can carry 212s), 1 İstif, 4 Adas, Ufuk, 5 LSTs without hangars, Derya(with space for 1+2) 4 oilers and 3 sub rescue ships without hangars. That's a total of 31 hangar spaces and 12 ships without hangars. As well as Anadolu with up to 30 helicopters. Its light load we've seen so far in exercises is 3 AH-1Ws, 3 Cougars and 2-3 Seahawks, i'll take it as a simple 10. So that's 43 heli spots+Anadolu. We have 23 Seahawks, 4 212s and 8 AH-1Ws. Of course, even in a perfect world, helicopter/ship number will not be 1/1. All these aircraft are land based when not deployed, not ship based.
With the planned navy enlargement program, we will lose the 4 older Mekos, but will add 7 İstifs and 10 OPVs in a decade or so, increasing our hangar size to 43 from 31 on our surface combatants. T625N could be used on all OPVs, and in all kinds of general purpose missions. They can be deployed on oilers for VERTREP missions, used in anti piracy missions on OPVs, can carry strike teams, missiles, torpedos, sonobuoys.
