Helicopter
Unlike most other categories of aircraft, the introduction of the tri-service designation system in 1962 did not result in a wholesale redesignation of helicopters. While six types received new designations in the unified, "re-started" sequence, the original "H-" series of designations that started in 1948 was also continued, and no further types of rotorcraft have been designated in the "post-1962" system.
- H-1 Iroquois / "Huey" – Bell Helicopter (Formerly H-40 / HU-1)
- H-1 Cobra / SeaCobra / SuperCobra / Viper – Bell Helicopter
- H-2 Seasprite – Kaman Aircraft (Formerly HU2K)
- H-3 Sea King / "Jolly Green Giant" – Sikorsky Aircraft (Formerly HSS-2)

Spaceplane
The only designation in the "Spaceplane" series, the MS-1A shares a designation letter with the anti-submarine warfare category, and is perhaps unique among MDS identifiers as being assigned to a future, and currently not wholly defined, concept, as opposed to a specific project.
Tanker
No specialised types have been acquired to receive a stand-alone 'K for Tanker' designation; for aircraft modified for use as tankers, see the parent aircraft in the proper sequence.
Trainer, 1962, 1990–present
Despite the adoption of the unified Mission Designation System in 1962, only two aircraft were designated in the new series, both former Navy types. The old series continued in use until 1990, at which point a new series was started over at T-1, with the previous T-2 still being in use. However, the old series has still seen new designations being assigned. The next designation available in the 'T' series is T-52 or T-7, depending on which series is continued.
