As with the scanners and ECM, I am prepared to overcome my reluctance to write house rules for the sake of addressing the lack of HG rules for consumable supplies.
This is what I've come up with, and I'd be grateful for any thoughts or observations.
Consumable Supplies
Consumable Supplies covers three things: life support, missiles, and sand cannisters
Life Support
The ship design rules assume a standard "trip" of two weeks, for which a life support cost of Cr2,000 per stateroom is incurred. HG power plant fuel requirements are calculated on the basis of the power required to support four weeks' cruising (including time in jump space) without replenishment. It is reasonable to suppose, therefore, that the standard formula for living accommodation provision includes sufficient storage / handling facilities for four weeks' worth of life support (food, water, air etc.) so that a ship may stay in space for as long as the standard fuel load allows without extra provisioning.
For most civilian vessels, this will be all the provisioning required. Many military ships, however, have to be capable of being self-sustaining for much longer periods than this. In order to do so, they need to have additional space fitted out to carry additional life support supplies. The tonnage required is 1 ton per 40 personnel per additional week's worth of life support; and the cost of fitting out this space in an appropriate manner is Cr1,000 per ton. Life support supplies themselves are, of course, extra and must be paid for as and when required.
When a ship's life support supplies are exhausted it must replenish its supplies, either at a friendly spaceport, base or world, or by having fresh supplies brought to it by a resupply ship.
The life support requirement formula may also be used to calculate the supply requirements of personnel on barren worlds or in vacuum situations (such as on a permanent space station). On worlds with breathable atmospheres - even if the population is hostile - it will be unnecessary to import air and water may be available locally, meaning that the amount of life support supplies required will be very much reduced.
Missiles
A missile turret, whether single, double or triple, may fire just 3 times before its ammunition is exhausted.
A 50-ton missile bay may fire 15 salvoes before its missiles are exhausted.
A 100-ton missile bay may fire 20 salvoes before its missiles are exhausted.
If a missile-armed ship is to continue firing beyond these ammunition limits, space must be allocated for a missile magazine.
In ships with missile turrets, magazine space is allocated in blocks of 3 tons. Each 3 ton block allows for 20 triple turret reloads, or 30 double turret reloads, or 60 single turret reloads.
In ships with missile bays, magazine space is allocated in blocks of 15 tons. Each 15 ton block allows for 4 reloads of a 100-ton bay, or 6 reloads of a 50-ton bay.
The cost of fitting out a missile magazine with all appropriate racking, blast protection and handling facilities is Cr 25,000 per ton. The cost of the missiles themselves is extra, and works out at Cr 100,000 per ton.
When the magazine is depleted or exhausted, it can be replenished at a friendly navy base or missile depot, or replacement missiles may be brought to the ship by a friendly resupply ship. When supplying or resupplying a ship's missile magazine, the player must specify and record how many of the missiles have nuclear warheads and how many have conventional HE warheads, as a ship obviously cannot fire ordnance which it is not carrying.
Sand Cannisters
Sandcaster turrets may only fire three times before their ammunition is exhausted. To continue firing beyond this ammunition limit, space must be allocated within the ship for a sand canister magazine.
Space for sand canister magazines is allocated in blocks of 3 tons. Each block of 3 tons allows for 20 triple turret reloads, or 30 double turret reloads, or 60 single turret reloads. The cost of fitting out is Cr 5,000 per ton. The cost of the sand cannisters themselves is extra, and works out at Cr8,000 per ton.
When the magazine is depleted or exhausted, it can be replenished at a friendly navy base or sand depot, or replacement cannisters may be brought by a friendly resupply ship.
NOTE: Missiles cannot be stored in sand canister magazines, nor sand canisters in missile magazines. The fitting-out of the two types of magazine is entirely different and neither is appropriate to the other.
This is what I've come up with, and I'd be grateful for any thoughts or observations.
