Ma devo fare tutto da solo?!?
(è stato sufficiente consultare Wikipedia)
Anche qui esisteva una versione Basic (M31) ed una Improved (M50) ...
" ... Development of an upgraded Honest John, M-50, was undertaken to improve accuracy and extend range.
The size of the fins was greatly reduced to eliminate “weathercocking” (the tendency of crosswinds to turn a rocket to face into the wind). Increased spin was applied to restore the positive stability margin that was lost when fin size was reduced. The improved M-50, with the smaller fins and more “rifling”, had a maximum range of 30+ miles with a scatter on target of only 230 metres (250 yd), demonstrating an accuracy approaching that of tube artillery. Honest John was manufactured by the Douglas Airplane Company of Santa Monica, ..."
Info sulla "copertina" ...
" ... The solid propellant filler of the rocket motor weighs over 1 ton. It burns for 4.5 seconds and delivers a 90,000 pound thrust. At burnout, the rocket has a velocity of 2,500 feet per second--about 1800 miles an hour. The propellant is a multiperforated double-base composition which can be stored and fired at temperatures from 0° F to 120° F.
An electrical heating blanket covers the entire rocket prior to firing. Thermo-statically controlled heating elements within the blanket attempt to keep the propellant at the optimum temperature of 77° F when the ambient temperature falls below this. At higher ambient temperature the blanket acts as an insulator. When the assembled rocket is being transported on its M329 trailer, power for the blanket is supplied by a 3,500-watt gasoline driven generator mounted over the left wheels. When mounted on the launching rail, power is supplied by another generator mounted on the launcher ..."

Honest John aveva anche un fratellino più piccolo, Little John.
