My Dad flew PBJ’s equipped with the smaller wing-mounted rockets (4 on each wing) with VMB -433. The idea was to provide close air-ground support during the invasion of mainland Japan.

Thanks for those, Mark, very interesting.

Interesting how these rockets attach to supports actually mounted onto the moveable bomb bay doors.

That dog will hunt...

Question if anyone knows. After the "success" of the Doolittle raid using army bombers off of american flat tops, was there ever any further testing or thoughts to a mitchell with folding wings?

Probably not, they would have to beef up the landing gear, and reinforce the tail so that it won't get ripped off during carrier landings by the tail hook, put folding wings wouldn't be too hard, but all these improvements would put the Mitchells weight way overboard, with the carriers having straight decks can you imagine a 25 missing the wires and crashing into all the aircraft parked on the bow.

On a side note, was there any thought to launching another raid using B-25 off a carrier during World War II ?

British Pathé has video that appears to show a turret mounted version of the 5 inch rocket launcher. The voice-over seems to suggest that both systems are versions of the Tiny Tim, but I think it is just the way the film is cut:


The nose mounted unit was also mentioned in the March 1947 issue of Popular Mechanics:

Similar to a number of designs from other sources, the Navy patented a rocket launcher that may be the version in the PBJ:

If anyone is interested in this sort of weapons testing, more pictures can be found on the China Lake Alumni website.


I remember being told that the B-23 was originally considered for the Doolittle Raid, but that the wings were too long for the carrier deck.
