  2. Jul 17, 2012 The older Military Generators were designed to keep lighting and essential equipment running. At that time, there was not a lot of computer use like there is today. The Generators were not real stable for power. If you hook one of those up to your house, today, don't use anything computerized. Refridgerator, Stove, if computerized.

Tactical Quiet Generators

Subsequent developments in several countries made the field telephone more practicable. The wire material was changed from iron to copper, devices for laying wire in the field were developed and systems with both battery-operated sets for command posts and hand generator.

Changing requirements and maintainability problems with the MIL STDs led to a need for generators with greater mobility, improved reliability/maintainability, enhanced survivability (e.g., Electro - Magnetic Pulse (EMP)), reduced infrared and acoustic signatures and lower acquisition and operation and support (O&S) costs.

Thus in 1988 and 1989 the PM developed and released purchase descriptions for a new family of generators -- the Tactical Quiet Generators (TQG)s. Libby Corporation won the contract to develop the 5-60kW generators, and Fermont Division the 3kW TQG. In December 1993 the 5-60kW sets first entered service at Fort Bragg, NC in the 82nd Airborne Division, and fielding has continued ever since. Because the contractor was unable to meet the overly stringent performance requirements, the 3kW contract was terminated in February 1995. A replacement program began in February, 1996.

The Tactical Quiet Generators (TQGs) are the latest generation of military generators for use by the Armed Forces. They were developed in response to the changing military threats, new strategies, and fiscal constraints which dictated improved battlefield survivability, enhanced deployment/maintainability and reduced operating and support costs. These military generators use predominantly commercial components, and provide a 'Quantum Leap' in performance for the Standard Family of DoD Generators.

The TQGs are skid or trailer mounted generator sets, are 'single-fuel' compliant (operate on diesel/JP fuels), have radically improved survivability, mobility, reliability and maintainability (see the benefits chart). Noise has been reduced to 70 dbA or less, quiet enough to reduce detection ranges from over a mile to less than 400 meters. The sets are undetectable from the front and sides by ground or airborne FLIR. Weight and size has been reduced by 20%, improving mobility and deployment. Significant improvements (16-19%) were made in maintainability (MTBF) and serviceability (PMCS) -- reducing both cost and manpower support costs. Finally, reliability has improved by over 100%. Moreover, they have reduced overall life cycle costs through reduced acquisition costs, lower fuel consumption and reduce O&S costs. Actual sample data collection from fielded sets indicates an average Operational Readiness (OR) rate of 96-99% (depending on size). In Haiti, even under extreme operating and environmental conditions the new TQGs achieved an 89% readiness rate -- orders of magnitude better than the old MIL STDs.

Battlefield survivability has been markedly improved by reducing noise by 80%, virtually eliminating IR signatures, and by hardening them against Electromagnetic Pulse (EMP) effects. Mobility has been enhanced by reducing weight and size, and maintainability/support has been improved by doubling reliability which reduces Operations and Support (O&S) costs.

Key

Additional funding placed in the Army power generation budget over the FY99-01 timeframe has helped to stem the continual aging of the fleet. However, considerably more funding will be necessary to reverse the aging of the fleet and accelerate the fielding completion.

As of mid-2001, winterization kits for the 5-60kW Tactical Quiet Generator (TQG) Family was under development. These kits will be available to units that require power in climates -25 deg F or below. Units will requisition individual kits by NSN and (kW) size. NSN assignment expected 4th QTR FY 99. Kit availability was expected for the 1st QTR of FY00.

Fielding of the 5 through 60kW generators began in December 1993. TQGs have been purchased and fielded by the Army, Air Force, Marine Corps, and several Allied Nations.

Military Standard Generators

The next effort undertaken by the PM was to develop and establish the first true Standard Family of Generators for DoD -- what is now known as the Military Standard (MIL STD) family. Beginning development in the late 1960's, these new generators were developed and designed by the government, and over 90,000 were procured from industry from 1968 through the 1987. The new MIL STD Family further reduced the number of makes/models of generators to 37; they included both gasoline and diesel sets from 0.5 to 750kW.

History

This MIL STD Family was the workhorse of the Services throughout the 1970's and early 1990's, with distinguished service in Grenada, Panama, Somalia, Desert Storm, et al. Because of funding limitations, even today, virtually all the the Reserves and Guard Forces rely on these aged sets. The average age of the Army's MIL STD fleet is 25 years on the small sets (3kW and below) and 18 years for the 5-60kW sets -- in many cases older than the soldiers/airmen/marines operating them.

History Of Military Key Generators Reviews

The 4,500 EMD Plants consist of three generator units each capable of producing 1,500 kW of power at 4,160 VAC at 60 hertz.

750kW Mil-Std Prime Power Generator(MEP 012A)

The prime power generator used in the USAF's Harvest Falcon/Eagle Bare Base and Army's 249th Engineer Bn Prime Power Support programs is the MEP-012A. The MEP-012A is a trailer mounted, diesel driven generator set, classified as 750kW, prime power (Type II), utility (Class 2A), Mode I (50/60 Hz) as defined in MIL-STD-1332.

The MEP-012A uses a liquid cooled, turbocharged, V12 diesel ( Cummins KTA-38) and a three phase, four wire, wye connected alternator ( Marathon 682FDR8419GH). Each MEP-012A weights approximately 25,000 pounds and consumes fuel at a rate of 55 gallons per hour at full power. The physical dimensions are as follows: Length=241 inches, Width=96 inches, Height=101 inches.
