TL-14 7500 Mj Meson Gun (spinal mount) 1/ Length = 180m (arbitrary figure, this will fit on a 4000 t Open Frame, 8000 t Needle or 20000t Wedge) 2/ Discharge Energy = 7500 Mj (again arbitrary...) 3/ a) Effective length = 180 x 1.2 = 216 m b) Tunnel volume = 13,500 m^3 c) cross sectional = 75 m^2 (bore size = 9.77 m) d) mass = 8100 t e) price = MCr 1350 4/ Effective range = 216,000 km 5/ Beam pointer: 210,000 km (7 hexes) Weapon short range = 210,000 km V = 4.2 m^3, M = 4.2 t, P = MCr 0.42 6/ Damage: DV = 5*(I^0.5) I = DE/(R/EL)^2 (round (R/EL)^2 to nearest 0.5 Short range: I = 7500/(210/216)^2 = 7500/1 = 7500 DV = 433 Med. range : I = 7500/(420/216)^2 = 7500/4 (3.78 rounds to 4) = 1875 DV = 216 Long range : I = 7500/(840/216)^2 = 7500/15 (15.12 rounds to 15) = 500 DV = 112 Extr. range: I = 7500/(1680/216)^2 = 7500/60.5 (60.49 rounds to 65) = 124 DV = 56 7/ a) Input energy = 7500/0.2 = 37500 Mj b) Homopolar generator (37500 Mj capacity) V = 1500 m^3, M = 3000 t, P = MCr 15 d) Power requirements: ROF 10 = 208.3 MW ROF 50 = 1041 MW ROF 100 = 2083 MW 8/ Crew = (tunnel volume / 100) * control point multiplier = 13500/100 * 0.25 (CPM @ TL-14) = 34 (to nearest 1) 34 x Crew workstations V = 238 m^3, M = 6.8 t, P = MCr0.068 Summary: TL-14 7500 Mj Meson Gun (Spinal Mount) V = 15242.2 m^3 Power: ROF 10 = 208.3 MW M = 11111.0 t ROF 50 = 1041 MW P = MCr 1357.088 ROF 100 = 2083 MW Damage = 7:433 14:216 28:112 56:56 The Model 75M3 Meson Gun is probably the smallest spinal weapon found in line-of-battle ships in the Solomani Navy. The 75M3 is installed in (among others) the 8000 t Diaz Class Auxilliary/Light Cruiser, as well as the 15000 t Moglichen Class Light Cruiser. The weapon has also been adapted for use in deep site planetary defense batteries. Michael Bailey (pd82495@wapol.gov.au)
