ArcLight Extended Range Cruise Missile

The BGM/RGM/UGM-132 Arclight Cruise Missile(Stylized as ArcLight) is an Extended Range, All Weather, Super Sonic Cruise Missile. Introduced by Raytheon in the 2020's, it was designed as a long- to Extended-Range, low altitude missile that be could be launched from a surface platform such as a Naval Ship or a towed battery.

Origins
In 2018 the Tarakian Navy issued a request to replace the BGM-109C Tomahawk Land Attack Missile (TLAM-C) with a unitary warhead and the BGM-109D Tomahawk Land Attack Missile (TLAM-D) with submunitions. The request called for an extended range cruise missile with a range greater than 2000 miles.

Early Planning Stages
The ArcLight was meant to be an advanced and complex missile, this called for advanced components including a new solid-fuel rocket booster capable of the 2,000+ miles. Guidance also needed to be upgraded, GPS, INS and TERCOM (Terrain Contour Matching) and DSMAC. These systems would also use Fiber Optics to improve the accuracy and reduce the weight.

Development and Production
By 2021 Raytheon began to modify select BGM-109C Tomahawk Land Attack Missiles to ArcLight Experimental Configuration (AXC) to test the new solid-fuel rocket boosters, and the new guidance systems' after several test fires from towed batteries, Raytheon began to develop the ArcLight as it's own missile and developed a new body and wing structure for the ArchLight.

Early Deployment
In 2024 A (Flight V) Decatur Class Guided Missile Cruiser, Tracy Island (CG-76) successfully test fired two BGM-132B ArcLight Extended Range Cruise Missiles at a old captured Herzgovnian aircraft carrier.

Active Deployment
In 2026 the ArcLight Extended Range Cruise Missile entered service under the designation BGM-132B ERCM-B carrying a 3,000lb Unitary Warhead. Since it's introduction every surface ship and submarine carries the ArchLight.

ERCM Design
The ArcLight is based off the Tomahawk Land Attack Missile (TLAM), while this is it's most prolific feature, the ERCM is a unique missile of itself, utilizing the same 18 Feet 3 Inch body of the TLAM without the Booster. This was to give it commonality with the current vertical launch system in use by Tarakian Ships. The Folding Fins/Wings went through a radical redesign to cope with the extended range nature of the ArcLight, these Fins/Wings make use of an advanced lightweight but durable material. GPS/INS/TERCOM/DSMAC all make use of Fiber Optic wires to reduce the overall weight of the missile.

Mechanism
The ArcLight can use several methods of detonation with it's warheads, while the FMU-174 is the primary detonation fuze used in all the Missiles but the Block IV Gryphon. B-Model Unitary Warheads use direct impact with the FMU-174A Fuze, C-Model Combined Effects Munitions (CEM) use airburst with the FMU-174E1 Fuze, F-Model Anti-Ship/Sub Warheads use the FMU-174E2A Fuze for direct impact and depth explosion. Models A and G (Both Nuclear) use entirely different fuzes.

Stealth
The ArcLight has a low radar cross section and uses radar wave absorbing materials when flying above the radar.

Launch Platform
Each missile is stored and launched from a pressurized canister that protects it during transportation and storage and act as launch tubes. These canisters are used in Vertical Launch Systems. For submarine-launched missiles (called UGM-132's), after being ejected by gas pressure (vertically via VLS) or by water impulse (horizontally via torpedo tube), the missile exits the water and a solid-fuel booster is ignited for the first few seconds of airborne flight before transition to cruise. BGM-132's are primarily launched from surface vessels via the VLS while the UGM-132's are primarily launched from submarines.
