[ST:Voyager] Where does the USS Voyager get all of those photon torpedoes from?

When the USS Voyager first became lost there were serious supply issues. Photon torpedoes pack a whole lot more punch than a phaser bank due to their 1kg antimatter warhead, but torpedoes are in limited supply. Once the torpedoes are depleted there's no more to be obtained.

At first, Voyager's crew was very reluctant to use torpedoes. After a while they became very free in using torpedoes, to the point where torpedoes were being used on a regular basis and even became the weapon of choice.

Replicating the parts to build a torpedo housing is something I can understand. Its energy expensive but its doable. They also did this to build new shuttles. However, a torpedo housing without a warhead isn't very useful. That warhead is pure antimatter.

As Voyager is continually low on its power, where does this antimatter come from? Every kg of antimatter used to construct a new photon torpedo means one less kg for the ship's warp core.

Power reserves are often times critically low, and yet Voyager still seems to be able to fire photon torpedo spreads at any time without concern to remaining ammunition.

During the first part of their return, personal logs were filled with mentions of the criticality of resupply operations. Later though, as the situation settled somewhat, the drama of needing to be constantly resupplied wore off, primarily because it became much easier to barter with civilizations other than the Kazon. Many crewmen, including the senior staff, ceased discussing these now routine supply operations in all except regular status reports.

One good trade with a warp capable civilization easily provided enough to "top off the tanks" as it were, including the storage bottles for fabricating new photon torpedoes.
