STOP CYING : MAKE THIS TANK : CAN YOU ?
· Secondary (I) Armament System
- High-Energy, Direct-Projection Laser Gun: The FCS will be equipped with a high-power, extremely accurate, fully-stabilized laser gun. The FCS is envisioned as an ‘all-electric’ vehicle, which facilitates a laser gun that could be used against a variety of close-in threats. Among them are helicopters, drones, ground ‘soft’ targets, infantry and — in self-defense mode — against incoming enemy missiles. High-power laser technology for armament applications has successfully advanced beyond its infancy and nowadays is well established in outer space and airborne applications. The FCS laser gun application will probably be a ‘spin-off’ of these developmental efforts. Incontestably, laser gun technology represents a tremendous step towards independence from logistic support. There is no need for frequent ammunition resupply since it will be ‘firing’ variable, high-energy short pulses (bursts) of converted electrical energy. During target acquisition, a low-energy laser beam will be pointed at the target to verify ‘on-target’ position and the corresponding effective range. Subsequently, the low-energy beam will be
substituted with a short, high-energy pulse, ultimately yielding target destruction. A case in point is the USAF’s High-
Energy Chemical-Oxygen Airborne Laser (ABL), currently being developed to destroy ballistic missiles early in their boost phase of flight, immediately following their launch phase. A fullpower prototype baseline configuration laser module in the hundreds of kilowatts
class has already been demonstrated to meet stringent performance requirements. Another notable program is the U.S.-Israeli Tactical High-Energy
Laser (THEL), developed to engage and destroy incoming missiles. Though chemical laser technology is considered mature, a compact and transportable tactical laser weapon system, well integrated into a smaller mobile armored vehicle, remains to be demonstrated. Typical outstanding issues are integration of optics, energy pressurization system, radar, and command & control. To facilitate its development, the U.S. Army is already leveraging technology from the USAF’s space-based laser program. Finally, the U.S. Army’s fixed laser, based at the High Energy Laser Systems Test Facility (HELSTF) White Sands, N.M., and the Los Alamos National Laboratory (LANL) facility are both engaged in laser research for military applications. These developments and similar projects imply that future ‘spin-off’ versions, on a much smaller
scale, could be implemented in various, armored ground-to-ground and groundto- air offensive weapons and active self-defense applications. The highpower, direct line-of-sight (LOS) laser beam must have the ability to travel through the atmosphere at tactical operational
ranges (10-15 km) without detrimental losses from beam spreading, divergence, dispersion, diffraction and scattering. Additionally, it must
maintain its ‘self-focus’ characteristics and high-energy density, which are mandatory for achieving an effective target kill. Much has yet to be said about laser research and applicability, but, in the interest of time and space, this short overview will suffice.
