Here is something that can be installed on almost all starships but we have seen it only on the Enterprise-D
Anti-matter Spread
The anti-matter spread is a series of rockets carrying a small payload of Anti-matter charges that are short range weapons. The rockets can be fired easily as a last ditch effort to destroy a target.
The antimatter spread costs 5 + 1 per every 5 missiles per rocket pod with a limit of 15 rockets per pod. The system cost 5 power + 1 power per rocket fired. These rockets have a short and have a range. The range is 2/3,000/10,000/30,000 and they can produce 20 damage per rocket. Installed in groups of ten on the hull.
Although not normally installed on 23rd or 24th Federation starships there have been some starships that have had retrofitting that installed this weapons system such as the USS Enterprise NCC-1701-D during the Borg attack as a distraction weapon during an conflict with the Borg cube to hide the emissions of a shuttlecrafts infiltration behind Borg shields in an attempt to retrieve Captain Jean-Luc Picard.
Some species with new entrance into the space fairing community have these weapons attached to their hulls.
Example: A Galaxy-class
USS Enterprise NCC-1701-D
Antimatter Spread <8 x 10 = 80>
Number: 15
Spread: 3
Range: 2/3,000/10,000/30,000
Targeting Systems: Accuracy 4/5/7/10
Power: [5+1 rocket fired]
Damage: 20
Locations: Replacing the forward sensor pallet arrays in the saucer section.
Notes:
The weapons fire put out by the Enterprise fired can equal to three Type II Photon Torpedoes fired together. The result is more confusing than that of damaging against the Borg shields.
