T' soundtrack be also processed with volume normalization, noise reduction, clippin' reduction, shiver me timbers, and equalization (the resultin' sound, me hearties, though nay perfect, is far less noisy than t' original). http://en.wikipedia.org/wiki/MGR-1_Honest_John T' MGR-1 Honest John rocket was t' first nuclear-capable surface-to-surface rocket in t' US arsenal. Designated Artillery Rocket XM31, t' first such rocket was tested 29 June 1951 and t' first production rounds were delivered in January 1953. T' designator was changed t' M31 in September 1953. Aye aye! T' first Army units received their rockets by year's end and Honest John battalions were deployed in Europe in t' Sprin' o' 1954. Avast! Alternatively, t' rocket was designed t' be capable o' carryin' an ordinary high-explosive warhead weighin' 1500 pounds, even though that be nay t' primary purpose for which it was originally envisioned. Arrr! History and development Developed at Redstone Arsenal, Alabama, me hearties, Honest John was a large but simple fin-stabilized, unguided artillery rocket weighin' 5820 pounds in its initial M-31 nuclear-armed version. Blimey! Mounted on t' back o' a truck, HJ was aimed in much t' same way as a cannon and then fired up an elevated ramp, ignitin' four small spin rockets as it cleared t' end o' t' ramp. Begad! T' M-31 had a range o' 15.4 miles with a 20 kiloton nuclear warhead but was also capable o' carryin' a 1500 pound conventional warhead. Begad! Early tests exhibited more scatter on target than was acceptable when HJ was conventionally armed. Begad! Development o' an upgraded Honest John, M-50, was undertaken t' improve accuracy and extend range. T' size o' t' fins was greatly reduced t' eliminate "weathercocking" (the tendency o' crosswinds t' turn a rocket t' face into t' wind). Arrr! Increased spin was applied t' restore t' positive stability margin that was lost when fin size was reduced. Ya scallywag! T' improved M-50, with t' smaller fins and more "rifling", had a maximum range o' 30+ miles with a scatter on target o' only 250 yards, me bucko, demonstratin' an accuracy approachin' that o' tube artillery. Ahoy! Honest John was manufactured by t' Douglas Airplane Company o' Santa Monica, California. T' M31 consisted o' a truck-mounted, unguided, arrr, solid-fueled rocket transported in 3 separate parts. Before launch they were combined in t' field, matey, mounted on an M289 launcher and aimed and fired in about 5 minutes. Begad! T' rocket be originally outfitted with a W7 variable yield nuclear warhead with a yield o' up t' 20 kilotons o' TNT (84 TJ) and later a W31 warhead with three variants be deployed with yields o' 2 kt (8.4 TJ), 10 kt (42 TJ), arrr, or 30 kt (130 TJ). Arrr! There was a W31 variant o' 20 kt (84 TJ) used in t' Nike Hercules antiaircraft system exclusively. Avast, me proud beauty! M-31 had a range betwixt 5.5 and 24.8 km (3.4 and 15.4 mi). Begad! In t' 1960s Sarin nerve gas cluster munitions were also available for Honest John launch. T' 2 basic versions o' Honest John were: - MGR-1A (M31) was 27 ft 3in long, had an engine diameter o' 22.875in, a warhead diameter o' 30in (762mm), ya bilge rat, a span o' 104in, matey, weighed 5820 pounds (nuclear), and had a maximum range o' 15.4 miles. Begad! T' Hercules Powder Company X-202 rocket motor be 197.44in long, me bucko, weighed 3937 pounds, and had 90,325 pounds average thrust.[3] - MGR-1B (M50) was 24 ft 10.53in long, had an engine diameter o' 22.8in, a warhead diameter o' 30in, a span o' 56in, weighed 4332 pounds (nuclear), and had twice t' range o' t' M31. Ya scallywag! T' Thiokol composite propellant solid rocket motor had 150,000 pounds thrust. Avast! Production o' t' MGR-1 variants finished in 1965 with a total production run o' more than 7,000 rockets. Honest John's bulbous nose and distinctive truck-mounted launch ramp made it an easily recognized symbol o' t' Cold War at Army bases world-wide and National Guard armories at home. Even though HJ was unguided and t' first U.S. Ahoy! nuclear ballistic missile, it had a longer service life than all other U.S. ballistic missiles except Minuteman. T' system was replaced with t' MGM-52 Lance missile in 1973, ya bilge rat, but was deployed with NATO units in Europe until 1985 and National Guard units in t' United States as late as 1982. Conventionally armed Honest John remained in t' arsenals o' Greece, Turkey and South Korea until at least t' late 1990s. By t' time t' last Honest Johns were withdrawn from Europe in 1985, t' rocket had served with t' military forces o' Belgium, Britain, Canada, arrr, Denmark (non-nuclear), me bucko, France, Germany, Greece, me hearties, Italy, t' Netherlands, Norway (non-nuclear), South Korea, matey, Taiwan (non-nuclear), and Turkey...
