Type: Torpedo
Initally developed for the Akira class, the Pulse fire tube is a modification of the burst fire tube. The loading and pre-fire stages can hold up to four photons simultaneously, but the launch tube itself is only of sufficient size to fire one weapon at a time. The pulse fire tube fires four rounds in one second, then pauses for three seconds to reload with the next four photons. The overall rate of fire is therefore one torpedo per second.
