**9. Determine number of required crew**
Since it is hard to determine crew before you have all of the components that will require crew, I typically just use 1 person per 100 dTons as an initial estimate. The ship was estimated to be 12,000 dTons so the crew would be about 120 (if it were a free trader or something). Triple that for three shifts on a military ship and we have 360 crewmen as an estimate.

Since the actual crew of an Iowa Class Battleship is known, let's use that instead ... 2700 crewmen.

Just pulling numbers out of thin air, since I don't know the SRD well enough to know if they have a recommendation in another part of the rules, but I will call that 10% officers and 90% enlisted men.

270 Officers

2430 Enlisted

**a. Choose accommodations (cockpit, cabin, extended accommodations**
Let's take a moment to see what they did on the TL 9 Destroyer. They have a control cabin that "supports 30 crew on shift" with both "standard plus extended" that requires 324 spaces. Let's see if we can get the math to work for the TL 9 Destroyer, before we try it on the Battleship. Crew per shift = 30 / 3 shifts = 10 crew per shift.

Control Cabin, Standard (CCS) supports 3 people (2 crew +1 other), so 10/3 = 4 CCS = 288 spaces

Control Cabin, Extended (CCE) supports 1 additional person, so 10/1 = 10 CCE = 10 x 18 = 180 spaces

288 + 180 = 468 ... so that is not equal to 324 spaces. Let's try again.

Control Cabin, Standard (CCS) supports 3 people (2 crew +1 other), so 1 CCS = 72 spaces (need 10-3 = 7 CCE)

Control Cabin, Extended (CCE) supports 1 additional person, so 7 CCE = 7 x 18 = 126 spaces.

72 + 126 = 198 ... so that is not equal to 324 spaces. Let's try again.

Control Cabin, Standard (CCS) supports 3 people (2 crew +1 other), so 1 CCS = 72 spaces (need 10-2 = 8 CCE)

Control Cabin, Extended (CCE) supports 1 additional person, so 8 CCE = 8 x 18 = 144 spaces.

72 + 144 = 216 ... so that is not equal to 324 spaces.

I just don't know how they arrived at -324 spaces for the Control Cabin. Working the problem backward, there needs to be at least one CCS, so 324-72 = 252 spaces. Each additional CCE requires 18 spaces, so 252/18 = 14 CCE.

1 x CCS = 2 crew + 1 additional person.

14 CCE = 14 crew

Total Control Cabin = 16 Crew + 1 person. [shrug]

For the TL 5 Battleship, I will design the Control Cabin to accommodate 50% of the officers (270/2 = 135). That requires 1 x CCS (3 men) and 132 x CCE (132 men).

1 x Control Cabin, Standard (CCS) = 2 crew +1 other = - 72 spaces

132 x Control Cabin, Extended (CCE) = 132 crew x 18 = - 2376 spaces.

For accommodations, I will provide the 270 officers with single rooms and the 2430 Enlisted men with double occupancy rooms. The actual rooms are different, but this is a start for a first pass at assigning spaces.

270 Officers Standard staterooms + 1215 Enlisted Double staterooms = 1485 Standard Staterooms

Accommodations

- Control Cabin = - 2448 spaces [1xStandard & 132xExtended]
- Standard Staterooms (x1485) = - 71,280 spaces [270 S.O. + 1215 D.O.]
