Gravity Release Units

These lightweight systems are electro-mechanically operated and use gravity to release their payload. Covering carriage weights from 5 lb (2.3 kg) to 415 lb (188 kg), a positive separation is assisted by spring loaded sway braces or a soft release mechanism. Harris’ range of gravity release units are designed for smaller munitions on UAVs, light combat, Counter Insurgency (COIN) airframes and are also suitable for non-lethal stores like commercial, medical or humanitarian packages.

Hornet – Electro-mechanical Stores Release Unit (SRU)

This gravity release system weighs just 2 lbs. (0.9 kg) and can carry up to 50 lbs. (22.6 kg) on a single lug. Barely larger than a dollar bill, the Hornet is a micro-pylon solution. Along with an in-flight operable lock (IFOL), a hook-closed sensor and a crutching system that can accommodate a wide range of store diameters between 3 and 12 inches, the Hornet also incorporates an internal umbilical, permitting data transfer (MIL-STD-1760 signal subsets) between platform and weapon. Positive separation of the store is assisted by the four spring-loaded sway brace feet.

The Hornet is currently being integrated on several UAV platforms and is available as single, double and triple release systems.

Gnat and Gnat-HD – Electro-mechanical Stores Release Unit (SRU)

The Gnat weighs in at 6.2 lb (2.8 kg) with a carriage capacity of 220 lb (100 kg). The HD or Heavy Duty version weighs in at 11.1 lb (5.0 kg) with a carriage capacity of 415 lb (188 kg).

The Gnat also features a self-locking and an electro-mechanical release mechanism which simplifies loading and eliminates the need for cartridges and their associated time-consuming servicing cycle. First-line operation and maintenance is achievable without specialist skills, tools or test equipment. Second line servicing is required only annually, ensuring a low logistic footprint.

Both variants are available with a sprung soft release system and the Gnat’s low reaction load makes it particularly suitable for the lightweight construction of helicopters, small aircraft and remotely piloted vehicles. The Gnat is currently in service on the IOMAX Archangel and being evaluated on several development programs.

MALTS – Modular A Light Training System

The MALTS training system is designed to provide a reliable, low through-life cost, training solution for operational fighters and lead in trainers alike.  It achieves this through the use of an electro-magnetic, single-lug, store release unit compatible with most common NATO training stores. The entire system is low maintenance, requiring only a yearly inspection and the light rounds can loaded by two personnel with no need for a mechanical store loader.

The MALTS is available in two versions that use a common release module and electronics box to maximize logistic compatibility:

  • The MALTS 2STN carries two practice bombs in a low drag tandem configuration and is designed to allow the parent platform to be able to conduct unrestricted air combat maneuvers post embarked store release with no need to remove the MALTS from the aircraft. The 2STN can also be fitted with an adapter to allow carriage and release of a single Laser Guided Training Rounds (LGTR). The MALTS 2STN is in regular use on European F-16 Fighting Falcons.
  • The MALTS 4STN carries up to four practice stores in a compact 2 x 2 configuration. The MALTS 4STN is in regular use on the KT-1 turbo-prop trainer and is currently under evaluation on other platforms.
