Model 3, Self‑Propelled Howitzer (M3/SPH) -- The M3/SPH is a mid–late 1980s turreted 155 mm self‑propelled howitzer designed by Perinto Defense Systems. It is based on the M1 chassis, with the engine and sprocket moved swapped from the back to front, and a smaller idler wheel being added to the back. However, it has a worse engine due to lack of space. -- SPECIFICATIONS: Unit cost: $3.9 million Weight: 47.5 metric tons Length (hull, gun forward): 10.8 m Width: 3.35 m Height: 3.15 m Engine: Turbocharged diesel V8, ~800 hp Crew: 5 (commander, driver, gunner, 2 loaders/munitions handlers) Elevation: +65° / -2.5° Traverse (turret): ~9°/s Reload rate: 2–3 rounds in ~12–15 seconds (short burst, crew‑assisted); sustained 3–6 rounds per minute Max speed: ~37 mph (60 km/h) -- ARMAMENTS: - 1 × rifled 155 mm howitzer (HE, smoke, illumination, DPICM) - 1 × 12.7 mm HMG -- Other features/notes: - Assisted bustle autoloader / mechanical rammer - Electro‑mechanical ballistic computer (analog/digital hybrid) with precomputed firing tables; manual meteorological inputs supported; - Early laser rangefinder (LRF) - Basic two‑axis gyroscopic gun stabilizer - NBC protection and filtered ventilation system - Night vision image‑intensifier sights (Gen II) for gunner/commander - Optical system: reticle sights and LRF - Protection: Welded steel/aluminium hull and turret, spall liners, smoke grenade launchers, fire detection/extinguishing system -- Credits: me, myself, & I all songs are clean
