Is that weapon Overkill? Yes.
But is it Useless? I don't think so.
The first atomic artillery, nicknamed "Atomic Annie" is a 280mm cannon capable of firing artillery shells with tactical nuclear warheads. Twenty of the atomic cannons were produced at a cost of $800,000 each. The weapon weighed over 83 tons, with cannon and carriage, or 50 tons in firing position, and was more than 80 feet in length, the largest mobile artillery ever built.
Gun crews could set the cannon up and be ready to fire in less than 15 minutes using hydraulic jacks and winches. The atomic cannon could be be returned from firing position to traveling position also in 15 minutes, record time for any artillery of similar size. The huge gun is balanced on its nine foot circular base plate with jacks, enabling its crew (5 to 7 men) to move it through its full 360° traverse capability. The projectile and powder charge are loaded with the assistance of a power hydraulic ram.

little take on the 6 million dollar man Originally posted by Now_Then
Something faster than a chopper could be different, say fired backwards from a fast jet? Or from very high up?

By comparison, the smallest yield version of the W54 (10 tons) is two to four times as powerful as the 1995 Oklahoma City bombing, making the 250 ton version 50 to 100 times as powerful.
