    2 Torpedo tubes. 
    2 Probe launcher of "px2" class.
Defense:    
    6 Shield generators each supplying 225eu of protection with 72% absorption.  Power usage is 25eu per shield with a regeneration of 0.90%

Analysis:   This is the Constitution class from the original series.  It has a similar weapons load out to the Destroyer class, but with a great crew, it has superior damage control and can take a heavier beating in a fight.  It also has more reactor power available, so you can reinforce shields as needed.  With a cruise speed of warp 6.0, it can stay ahead of some heavy capital ships, but a heavy cruiser captain should prioritize small, fast ships as threats to avoid being swarmed.
