guidance is infrared, i.e., heat seeking. This missile is scheduled 
for use on the English Electric P-1 and the Gloster Javelin fighters. 
The Royal Navy will also use it with its DH Sea Vixens aircraft. 
The Red Dean, the third in the series, was being developed by 
Vickers-Armstrongs when it was rumored to have been canceled. 
In the air-to-surface category only one missile is reported to be 
under development. The missile is expected to be comparable in 
size to the U.S. Air Force’s Rascal, and its application is reported 
to be with the RAF’s Vulcan and Victor bombers. 
In the surface-to-air category there are three missiles, the Blood- 
hound, Thunderbird, and the Sea Slug. All are reported now in pro- 
duction. The Bloodhound is expected to be Britain’s first operational 
missile in this category. The second most publicized missile in this 
family is the Thunderbird. Performance of this vehicle is said to 
be on the same order as the U.S. Nike Hercules. The Royal Navy’s 
entry in this family is the Sea Slug, designed especially for naval 
defense. The missile configuration includes the wrap-around, solid- 
propellant boosters as well as a solid-propellant sustainer motor. It 
has medium-range interception capability and can reach any aircraft 
flight altitude necessary for interception. 
The surface-to-surface family boasts of only one vehicle, a 2,000- 
mile intermediate-range ballistic missile (IRBM). This vehicle has 
no known name at present. De Havilland in conjunction with Rolls 
Royce has prime responsibility for developing this missile for the 
RAF. The ICBM which was being developed by Vickers-Arm- 
strongs was canceled for undisclosed reasons. 
Among British Commonwealth missiles, Canada has made one at- 
tempt to develop an air-to-air missile, the Velvet Glove, but a change 
in government policy called for canceling it. Australia’s contribu- 
tions to date are the Jindivik subsonic bomber and the huge Woomera 
rocket test range. 
It is apparent that the British have accomplished and are achiev- 
ing a great deal in all phases of missile technology. In terms of 
trained manpower, research, and test facilities, the British Empire’s 
potential is excellent—a potential which should someday render 
her one of the top three leaders in this field. 
ITALY 
Italy, one of the pioneers in jet propulsion, has been interested in 
rocketry since the end of World War II. This interest has been dis- 
played by individuals, government, and industry. However, lack 
of funds and government direction has delayed positive action. In 
spite of these handicaps, however, Italy has developed several mili- 
tary rockets, two of which are the Airone and the Robotti. The
