The W54 graphite Ping shafts are a specific type of golf club shafts manufactured by Ping. The "W" likely refers to the weight of the shaft, with W54 indicating a 54-gram shaft. Graphite shafts are known for being lightweight and providing more flexibility, which can help golfers generate more clubhead speed. These shafts are designed to provide a balance of distance, accuracy, and feel for golfers looking for a lightweight option in their clubs.
The W54 nuclear warhead used in the Davy Crocket, AIM-26 Falcon air-to-air missile and the SADM atomic demolition munition was a variable yield, linear implosion warhead most likely with an unreflected bare ovoid pit. It boasted a variable yield of 0.01 kilotons (10 tons of TNT) or a variable yield variant of between 0.02 kilotons-1 kiloton. (20 tons of TNT - 1000 tons of TNT) The cost to develop this weapon is not that easy to find, but many estimates and research have shown a price of anywhere from 14 - 40 million per weapon, not including the delivery system.
