Convair NB-36H

Convair · United States · first flew 1955 · bomber

The Convair NB-36H was a modified B-36 Peacemaker used to test a nuclear reactor in flight as part of the US Aircraft Nuclear Propulsion programme; it is the only aircraft known to have flown with an operating nuclear reactor aboard.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Standard B-36 Peacemaker outline distinguished by a large blister over the forward bomb bay and a specially shielded crew compartment; visually similar to a standard B-36 at distance.

History

A B-36H was converted to carry a 1-megawatt air-cooled nuclear reactor in its bomb bay, with extensive radiation shielding and a new crew compartment with a 12-tonne lead and rubber shield. It flew 47 test missions between 1955 and 1957 to study the effects of a reactor on aircraft systems and crew radiation exposure, though the reactor was not used for propulsion.

Variants

The NB-36H was a unique one-off conversion; the X-6 nuclear-powered aircraft it was meant to inform was never built.

Where you'll see it

The NB-36H flew exclusively as a US Air Force research aircraft; the ANP programme was cancelled in 1961 and the aircraft scrapped.
