280 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1958 
most likely will first see service in the New York City and the Wash- 
ington- Baltimore areas. 
The Terrier, a Navy missile, is in operational use on the cruisers 
U.S.S. Boston, U.S.S. Canberra, and the destroyer U.S.S. Gyatt. The 
missile is 27 feet long and a foot in diameter; speed is 1,500 miles per 
hour, range about 20 miles, and ceiling 60,000 feet. The missile is 
boost launched and sustained by a solid rocket motor. By 1961, 
Terrier I is expected to be operational on approximately 22 capital 
ships. Terrier I, currently under development, is reported to be 
twice the size of the Terrier I. 
The Tartar, another Navy missile from this category, is a sub- 
stantially more efficient single-stage vehicle that is expected to replace 
Terrier I by 1961. The missile, currently in the early production 
phases, will be used as secondary batteries on large ships or de- 
stroyers, and on other smail vessels. 
At the present time the arsenal of short-range, surface-to-surface 
tactical missiles consists of four members: Honest John, Little John, 
Dart, and LaCrosse. The function of these short-range, surface-to- 
surface missiles is twofold. First, it must provide the infantryman 
with an effective weapons system for defending himself against all 
immediate fixed and mobile units; and, second, it must have the 
capability of reaching behind the immediate contact area to destroy 
selected targets. 
Probably the best known of this family is the Honest John. The 
Honest John is 27 feet long and 2.5 feet in diameter. The range 
of this weapon has been quoted as 20 to 30 miles. The vehicle is 
powered by a solid rocket motor and is an unguided, free-flight 
artillery rocket capable of delivering nuclear warheads. It is cur- 
rently assigned to the Army’s new pentomic divisions. The first tac- 
tical unit armed with this rocket was the 101st Airborne Division. 
The Little John is, as the name implies, a smaller solid rocket motor 
missile with a shorter range. It was designed to supplement the 
Honest John and provide all-weather artillery support. 
The Dart is one of the newest missiles that has been developed. It 
is 5 feet long, 8 inches in diameter, and has a 3-foot wing span. Speed 
is over 600 miles per hour. The range is unknown, although in one 
public demonstration the missile hit the target at a range of 2,100 
yards. The Dart is powered by a single-stage smokeless solid rocket 
motor and is wire guided. Since its range exceeds that of any known 
tank armament, it can be fired safely from a fixed or mobile position. 
The missile is in production but is not yet operational. 
The LaCrosse is a solid rocket motor propelled, all-weather, ground- 
support missile developed for the Army and the Marine Corps. It is 
20 feet long, 20.5 inches in diameter, and has a range of 15 to 20 
miles. The missile is truck mounted and extremely mobile. It is 
currently in production.
