The AIR-2A Genie was a Douglas-built unguided nuclear air-to-air rocket for Cold War bomber-interceptor defense. It used blast effect rather than terminal guidance, pairing a W25 nuclear warhead with modified F-89J, F-101B/CF-101B, and F-106A interceptor aircraft in U.S. and Canadian air-defense service.
The Genie designation changed as U.S. missile nomenclature shifted from MB-1 to the AIR-2 series, while training and later motor-upgrade rounds kept related but distinct designations.
| Variant | Configuration | Designation notes |
|---|---|---|
| MB-1 Genie | Original operational designation | Boeing heritage material says the weapon was designated MB-1 and became operational in 1957 before the later AIR-2 series redesignation. |
| AIR-2A Genie | Operational nuclear air-to-air rocket | The MB-1 became AIR-2A in the 1963 AIR-2 designation series; museum sources identify the AIR-2A as the nuclear-armed rocket carried by F-89J, F-101B, and F-106A interceptors.

| ATR-2A / ATR-2N | Training rocket | Boeing identifies the MB-1-T as ATR-2A and says the training rocket was also known as ATR-2N; the National Museum display example was received as an ATR-2N. Sources: Boeing Select Products - MB-1/AIR-2 Genie Missile, McDonnell Douglas Air-2A Genie Rocket |
| AIR-2B | Motor-upgraded rocket | Boeing says Thiokol began producing a longer-life AIR-2 motor in 1965 and that upgraded Genie rockets were designated AIR-2B after the mid-1970s. |
The Genie was built for bomber-interceptor aircraft rather than general fighter armament.
| Carrier | Carrier type | Carriage evidence |

 | F-101B/CF-101B interceptor aircraft | The National Museum identifies the F-101B as a primary AIR-2A carrier and lists two AIR-2A rockets in F-101B armament. Canadian museum sources document CF-101 Voodoo service with Genie nuclear-tipped rockets under U.S.-Canadian/NORAD custody and release arrangements.

The Genie was an interceptor weapon built around aircraft fire-control systems, rapid launch, and nuclear blast radius rather than missile guidance. Official museum pages identify the F-89J, F-101B, and F-106A as Genie-capable U.S. interceptors; Canadian CF-101 Voodoos also carried AIR-2A rockets in NORAD air-defense service.
The F-89J fired the 19 July 1957 live Genie test and carried two AIR-2A rockets with four AIM-4C Falcon missiles.

The F-101B carried two AIR-2A rockets; Canadian CF-101s later carried Genie rockets under U.S. custody and joint NORAD release arrangements.

The F-106A technical notes list one AIR-2A Genie and four AIM-4 Falcon missiles, with the MA-1 fire-control system able to manage the attack run and weapon release.
