The "Decimator" Metric Small Diameter Gliding Bomb (MSDGB) is a day/night all-weather capable unpowered precision-guided weapon with a low mass envelope and compact physical footprint with folding wings for internal weapon bay compression carriage on a quadruple multiple ejection rack for increased aircraft loadout. It can be launched in dive, toss, loft, and straight-and-level flight modes and delivered against single or multiple targets in a single pass to saturate targets by time-on-target attacks for increased kill probability. Variable-geometry high aspect-ratio wings allow an expanded launch envelope for delivery on-axis or off-axis from very low to very high altitudes to increase launch aircraft survivability by avoiding exposure to ground fire. it has a long stand-off glide range of 64 km (34½ nmi) using control surfaces, dual-mode active/passive sensors and two-way datalink to effectively engage fixed, relocatable and mobile targets with high accuracy to reduce the risk of collateral damage to nearby friendly structures and personnel.

Description

The MSDGB is based on the 100 kg (220½ lb) bantamweight Metric Ordnance Bomb Series (MOBS bomb body. It consists of a low-drag aerodynamic steel casing with ogival nose shape capable of high speed penetration performance when delivered at a steep terminal dive angle of up to 0.91 m (3 ft) in steel-reinforced (rebar) 5 ksi concrete under 1.83 m (6 ft) in soft soil or mud or 0.91 m (3 ft) in hard compacted soil. The kill mechanism is a 57.6 kg (127 lb) dense inert metal explosive (DIME) insensitive munition bursting charge with a low explosive yield and focused blast pattern, reducing the risk of fratricide and collateral damage. It is initiated by a electronic safe and fire (ESAF) device by a multi-mode electronic fuze with point detonation delay and intelligent void sensing to maximise after penetration effects, and proximity sensor for height of burst functioning. Terminal homing is provided by dual mode 94 GHz millimetre wave (mmW) active radar and mid-wave (3.5 – 5.0 µm) imaging infrared (IIR) passive focal plane array (FPA) sensors. The seeker contains field programmable gate array (FPGA) based logic that processes each sensor channel with non-cooperative target recognition (NCTR) algorithms to detect, locate and classify targets, including constant false alarm rate (CFAR) clutter rejection algorithms for high target/decoy discrimination, and fuses both sensor channels using pattern matching digital image correlation (DIC) and tracking algorithms to obtain precision range and track data to an aimpoint accuracy of 1 m (3 ft 3⅜ in) in all types of weather. An inertial-satellite (INS/GPS) navigation system using anti-jam receivers allows the weapon to be released at an off-axis angle of up to 90° with self-navigation to the target. A two-way datalink allows mid-course updates and human-in-the-loop control for inflight targeting/retargeting. A strongback wing assembly with jointed tandem scissor-type wings which fold for compression carriage and deploy into a high aspect-ratio diamond-shaped planform offers excellent glide and manoeuvre characteristics. A cruciform (X-shaped) tail steering assembly with all-moveable controls correct the flight trajectory for high cross-track manoeuvrability to avoid obstacles, navigate around terrain, and to track and engage mobile and relocatable targets.

Concept of operations

The MSDGB is designed to be employed in direct attack close air support/battlefield air interdiction (CAS/BAI) missions with high hit accuracy to engage targets at danger close distances to friendly forces in contact with the enemy. High tactical flexibility is provided by a programmable multi-option fuze that can optimize effects against fragment-sensitive targets e.g., personnel, equipment and supplies, and non-hard, semi-hardened, hardened and deeply buried targets including caves and tunnels, reinforced concrete structures e.g., bridge piers, bunkers and aircraft shelters, craterng and lifting slabs on concrete and asphalt areas e.g., roads and motorways and airfield runways, taxiways and parking aprons; and static and moving point targets e.g., soft and hard skin vehicles and armoured vehicles, and landing ships and craft. It can be preprogrammed with targeting data to attack preplanned targets, and can autonomously engage targets of opportunity using the sophisticated algorithms in the seeker (see above) in lock-on after launch (LOAL) mode to autonomously search, locate, identify, track and guide on to targets.

Variants

The MSDGB also forms the basis of the "Devastator" Ground-Launched Metric Small Diameter Gliding Bomb (GL-MSDGB) that is boosted to altitude with a 266 mm Mobile Artillery Rocket System free-flight rocket motor to achieve an unpowered glide range of 150 km (~81 nmi) for long-range precision fires to hold at risk targets over a 70,000 km² (~20,408 nmi²) area.
