Dragon Fire (mortar)
The Dragon Fire 120 mm heavy mortar is a program under development (as of 2006) for the US Marine Corps. It is a fully automated mortar capable of using rifled or smoothbore 120 mm ammunition. Like all mortars it is a high-angle-of-fire weapon used for indirect fire support. Dragon Fire is also expected to be effective in a counter-battery role.
History
The Dragon Fire program began in 1997 as a concept demonstrator, intended to experiment with automating medium-caliber, medium range artillery. The Dragon Fire combines digital fire control, power-operated traverse, elevation, and loading, and an advanced aiming system with a 120mm rifled mortar system to give much faster and more precise direct support. Program lead is the Marine Corps Warfighting Laboratory with design by Army Armament Research, Development, and Engineering Command (ARDEC), and fabrication by Rock Island Arsenal IL, and General Dynamics Ordnance and Tactical Systems (GD-OTS). The first prototype was constructed partly from components of a French 120 mm rifled mortar and was completed in 1998. The system was successfully tested and then used in operational experiments from 1998 to 2002, including firings from a modified Light Armored Vehicle.

Dragon Fire II intended to reduce the overall weight of the concept demonstrator and to improve its performance, particularly response time and precision and to facilitate counter-battery fire. The first Dragon Fire II concept demonstrator was completed in September 2005 at Rock Island Arsenal and successfully test fired at Yuma Proving Ground in November 2005.
Operation
The Dragon Fire mortar system can be deployed mounted in an LAV, towed by a HMMWV, or air deployed by CH-53 Sea Stallion helicopter or V-22 Osprey. Mounting in an LAV does not require a separate mount; its towing carriage can be converted to an LAV mount in five minutes. After deployment the crew can control the weapon system from a remote station. In operation it is designed to be fully automatic: loading, computing firing solutions, aiming and firing automatically. From an unloaded condition, the weapon is capable of loading, completing a firing solution, aiming, and firing the first round within 14 seconds of receiving an order. The weapon is also capable of being operated manually in the event of failure of an automatic system.
The advanced fire control system is fully compatible with the US Army system, to reduce the risk of friendly fire.
Types of Rounds
The Dragon Fire system is designed to be able to use all NATO types of rifled and smoothbore 120 mm mortar ammunition.
