US Tank Concepts NO.1 – 1-B (1968)

CONCEPT NO.1 COMBAT VEHICLE, TURRET, CANON

Concept Description and Design Rationale

 

(C) This design study, mounting a cannon in a turret, is intended to explore the configurational parameters of a combat vehicle system that will exploit the capabilities and advantages of future cannon technology, without the design constraints imposed by a missile system.

(C) This conceptual approach provides the smallest frontal silhouette possible in a turreted configuration, combined with an inherent high degree of ballistic protection in the critical 60 degree frontal attack zone.

(C) The weapon would be capable of fully stabilized fire on the move trough 360 degrees of rotation.

 

(C) Characteristics and Outstanding Features

 

a. Weight: 38-43 ton

b. Width: 138 inches

c. Height (top of turret): 85 inches

d. Height (overall): 92 inches

e. Length (overall): 352 inches

f. Ground pressure: 8.2-9.3 psi

g. Variable ground clearance: 6-24 inches

h. Primary armament: 110-120mm Cannon

i. Three man crew seated low in vehicle for minimum exposure to enemy fire.

j. The concept has a potential for ruggedness reliability and relative simplicity

k. Minimum frontal silhouette.

l. Remotely located and controlled rapid fire weapon system.

m. Relatively low cost ammunition.

n. Stabilized main armament with automatic loader.

 

 

Disadvantages

(U) Configuration is not adaptable to planned radio-logical and shaped charge protective measures.

CONCEPT NO.1-A COMBAT VEHICLE, TURRET, CANON

 

Concept Description and Design Rationale

(C) This design also shows a turreted tank mounting a cannon of approximately 110mm size. This conceptual approach is intended to determine the optimum turret to best exploit the many advantages of current and future cannon technology. The cannon weapon system, with its many types of projectiles will continue to play an important role in future combat vehicles.

(C) This type of turret configuration provides a small frontal target area compared with conventional turrets. The turret provides frontal protection trough 30 degrees of horizontal angle on each side of the vehicle against current size kinetic energy projectiles at short attack ranges. An added bonus is that angles for attack less than 30 degrees, the protection increases. This means that the turret side walls are practically invulnerable trough approximately 80% of the 60 degree angle of attack.

(C) The principal difference between this concept and the previous one is that the weapon has been moved forward in this design, to premit a different type of automatic loader to be considered. In the first concept the weapon had to be brought to a certain angle of elevation to be loaded. In this concept, the weapon can be loaded at any angle of elevation by means of a tray that can be aligned with the weapon.

 

(C) Characteristics and Outstanding Features

 

a. Weight: 43 ton

b. Width: 138 inches

c. Height (top of turret): 92 inches

d. Height (overall): 92 inches

e. Length (overall): 376 inches

f. Ground pressure: 9.2 psi

g. Variable ground clearence: 6-24 inches

h. Primary armament: 110-120mm Cannon

i. The advantages and features listed for the previously shown concept are also applicable to this study. The earlier noted disadvantages would also apply.

CONCEPT NO.1-B COMBAT VEHICLE, TURRET, CANON

 

Concept Description and Design Rationale

(C) This concept also employs a cannon as the primary armament system. The intent of this concept was to explore the design trade-offs of an automatic versus manual loading for this type of turret configuration. We must not conceder an automatic loader as the preferred loading method in all future designs. The overall design of the system will determine whether or not an automatic loader is a well integrated asset or a space claiming liability.

(C) In this design the loader is seated to the left of the weapon and loads the required round into a loading tray that is hinged from the gun mount. The tray is raised to the weapon elevation and the projectile is loaded. This facilitates loading in the stabilized mode of operation. The breech block moves upwards to open, thus providing more loading space between the weapon and the tank commander.

(C) The tank commander is seated in the bustle directly behind the weapon. In this location he has excellent all round vision. The remotely operated rapid fire weapons system is located in the bustle behind the commander.

(C) This concept is shown with the 1500 horsepower turbine currently under development.

 

(C) Characteristics and Outstanding Features

 

a. Weight: 45 ton

b. Width: 138 inches

c. Height (top of turret): 95 inches

d. Height (overall): 99 inches

e. Length (overall): 372 inches

f. Ground pressure: 10.3 psi

g. Variable ground clearence: 6-24 inches

h. Primary armament: 110-mm Cannon

i. Four-man crew

j. Previously mentioned advantages, disadvantages and features for this type of vehicle are also applicable to this concept.
