Explosive Payload

Description
It is important to be able to protect the shuttle from viral payloads, and hence destroy payloads deposited by other countries quickly and easily. If you should accidentally destroy useful payloads that other agencies have laid out you really can't be blamed for simply being too concerned about the shuttle's welfare.

Cost
FREE

Impact
An explosive payload can be attached to any missile chassis for free. When it euphemistically 'deposits its payload' it just destroys any othe payloads there (note this is not a new rule; the explosive payload is 'nothing' and so when 'nothing' is deposited over the top of another payload it will destroy it and replace it with 'nothing')
