Re: Nelson Mandela-class Diplomatic Courier
The point I was making is that diplomatic vehicles are typically unarmed. Air Force One doesn't carry air to air missiles. Defensive countermeasures, yes, but weapons?
It always struck me as odd that there were so very few anti-torpedo countermeasures in Starfleet, aside from shields. Interceptor torpedoes and point defense phasers (like in ST:Armada) would have been neat. Even modern-day Fedex planes have countermeasure systems designed to feed incoming missiles a false target (like how O'Brien defeated the Cardassian weapons platforms) and then automatically signal air traffic control of the attack.
