TOBYHANNA ARMY DEPOT, Pa. -- Even the toughest Marine needs top--notch equipment and support to bring the fight to the enemy. Tobyhanna Army Depot now provides more of that support. Technicians have begun supporting two Marine Corps surveillance radars.
The support, for the AN/TPS-59 (V) 3 Long Range Surveillance Radar and the AN/TPS-63B Medium Range Surveillance Radar, is in addition to the AN/TPQ-46 Firefinder support mission that began last year.
The TPS-59(V)3 provides coverage for all air traffic as well as tactical ballistic missiles in the area and, at 30 feet tall, is the largest radar system in the Marine Corps. The mobile radar supports anti-air warfare operations, enroute traffic control to a distance of about 300 nautical miles and theater missile surveillance to about 400 nautical miles.
The AN/TPS-63B radar automatically detects aircraft in heavy ground clutter, heavy rainfall and electronic interference. The mobile radar provides air surveillance in three selectable ranges of 80, 120 and 160 nautical miles with a time-shared display of radar and Identification Friend or Foe data.
"We will repair and test all the RF (radio frequency) equipment, including transmitters and receivers, and power supplies," said Electronics Engineer Rick Bekanich of the Production Engineering Directorate. "Tobyhanna will also repair mechanical components as well, such as motors, gearboxes, antennas and antenna drives."
One of each system is here now and once they are repaired, they will be tested at the depot's new radome and tower facilities on Powder Smoke Ridge. Bekanich said the depot will repair and test two TPS-59s and three TPS-63s per year.
"We will also repair and test what are called 'secondary depot repairables,'" said Ed Panner, an electronic integrated systems mechanic in the Intelligence, Surveillance and Reconnaissance Directorate. "Those are radar components, but not entire radars."
Four technicians spent months at Maintenance Center Barstow (MCB) at Barstow, Calif., for on--the--job training on the systems and trained other technicians when they returned. Panner noted that the new mission is not difficult for technicians, but establishing processes has proved challenging.
"Everything has to be First Articled," he said, referring to the process by which depot personnel show customers that they can repair a system or component correctly, called First Article Testing.
"We've also ordered new test, measurement and diagnostic equipment, and the Engineering Lab made test fixtures," he added.
A hot mockup, a working system used for testing, will be used to assist in troubleshooting AN/TPS-63B system and components.
Once systems are tested, Tobyhanna personnel will provide fielding support for Marine Corps units.
Tobyhanna Army Depot is the Defense Department's largest center for the repair, overhaul and fabrication of a wide variety of electronics systems and components, from tactical field radios to the ground terminals for the defense satellite communications network. Tobyhanna's missions support all branches of the Armed Forces.
About 5,600 personnel are employed at Tobyhanna, which is located in the Pocono Mountains of northeastern Pennsylvania. Tobyhanna Army Depot is part of the U.S. Army CECOM Life Cycle Management Command. Headquartered at Aberdeen Proving Ground, Md., the command's mission is to research, develop, acquire, field and sustain communications, command, control computer, intelligence, electronic warfare and sensors capabilities for the Armed Forces.
