Mk- 7 Nuclear Bomb
Initially produced in 1952, the Mark 7 was the first nuclear weapon which could be carried by fighters.  Although they carried it externally, it could also be carried internally by bombers such as the B-57.  Capable of either an air or ground detonation, the Mk-7 had a yield in the kiloton range. It became obsolete in 1967 and is no longer in service
Mk-28 Nuclear Bomb
This "hydrogen" bomb was first produced in 1958 and is still seeing active service.  It was designed to be carried by various fighter and bomber aircraft.  The "28" warhead was also used in Hound dog and Mace missiles which are now retired. This weapon is capable of a ground or air burst and may be carried internally or externally, with a free-fall or parachute retarded drop, depending upon its configuration
Mk-39 Nuclear Bomb
An improved Mk-15 that came into service in 1957. It was carried by B-47 and B-52 bombers.  It featured a shock-absorbing aluminum honeycomb nose and used four parachutes for retarded deliveries.   The Mk-39 weighed 10,000 pounds and had an explosive yield measured in megatons.  The last one was  removed from service in 1966.
Mk-53  Nuclear Bomb
First produced in 1962, it was designed to be carried internally by B-47, B-52, B-58, and B-70 aircraft. It was equipped with five parachutes to retard delivery.  If for some reason a free-fall delivery was required, the parachute "can" could have been blown out, thereby jettisoning all chutes. With a yield in the megaton range. they can be configured for air burst, contact burst, and delayed action detonation. The Mk-6 re-entry vehicle installed on the Titan II ICBM contained a W53 warhead, basically the same as the Mk-53 bomber version.
