B61 administrative procedures performed by ground-based personnel are executed via an access panel located on the side of the bomb, which opens to reveal 9 dials, 2 sockets and a T-handle which manually triggers the “command disable” function. One of the sockets is a MC4142 “strike enable” plug which must be inserted in order to complete critical circuits in the safety/arming and firing mechanisms. The other socket is the PAL connector located in the top right hand corner of the arming panel, which has 23 pins marked with alphabetic letter codes.
The B61 also features a “command disable” mechanism, which functions as follows: after entering the correct 3-digit numeric code it is then possible to turn a dial to “DI” and pull back a T-shaped handle which comes away in the user’s hand. This action releases a spring-loaded firing pin which fires the percussion cap on an MC4246A thermal battery, powering it up. Electrical power from the thermal battery is sufficient to “fry” the internal circuitry of the bomb, destroying critical mechanisms without causing detonation. This makes the bomb incapable of being used. Any B61 which has had the command disable facility used must be returned to Pantex for repair
Can the fissionable material in an inert weapon be extracted for use elsewhere? THAT is what I would worry about with an islamuck country.
