H-21s were the Army’s main battle helicopter in Vietnam until the late part of 1963.
As far as I know, there never were any bombers used by the north, or attack aircraft either. In the early 80s the J.A.S.D.F. intercepted a Vietnamese bomber entering their airspace. It was a Beagle, camoflaged and wearing north markings. I was very tempted to borrow that photo when I saw it.
Never heard of any either…But had they done it, they would have caught us, pants down, at least for the first couple of strikes. Not much down south or in Thailand for AA defenses. At least that was obvious.
The North did have a squadron of IL-28s during the war but never used them in combat. They did do a strike on a CIA station in Laos using AN-2 Colts. IIRC, one was engaged and shot down by a UH-1. They also used some bombed up Mig-17s to do an air strike on USS Higbee and USS Oklahoma City which ere doing shore bombardment of North Vietnam during the Easter Invasion of 1972.They actually scored a hit on USS Higbee, destroying the after 5” turret during that strike.
Illustrating why those 5" mounts are more properly reffered to as gun rooms.

Thought about this thread just the other day–an image popped up in my feed of a USAF EC-121 in full SEA camo. ind of striking to see a Connie like that.
