Lockheed Completes First of New Air Force Radars

SYRACUSE, New York — Lockheed Martin has wrapped up production of the first of the Air Force’s new long-range air defense radars, the company recently announced.

In March, the Air Force announced it had selected the AN/TPY-4 for the Three Dimensional Expeditionary Long Range Radar, or 3DELRR, rapid prototyping program worth $8.4 million. The new ground-based radar is able to detect and track current and emerging threats, from small unmanned aerial vehicles to tactical ballistic missiles at great distances, said Rick Herodes, director of ground-based air surveillance radars at Lockheed Martin.

What sets the TPY-4 apart from other radars on the market is its software-forward design, Herodes said.

“If you imagine older style radars as putting out beams and receiving energy back, they kind of did it as an entire antenna,” he told reporters during a tour of Lockheed Martin’s facility in Syracuse, New York.

The TPY-4 radar, however, has more than 1,000 individual mini-radars the size of a hockey puck that can be independently and digitally controlled, Herodes said. This allows users to make software changes without altering the radar’s hardware, he said.

“Each one of those pucks can transmit independently and receive independently and act as its own radar. So, we could change how the radar transmits and receives so that part of the antenna can do one thing and another part of the antenna could do another,” he said.

The open architecture also gives the radar additional flexibility to detect the specific threat a user is facing, he added.

Chandra Marshall, vice president of radar and sensors systems at Lockheed Martin, noted the software-defined architecture will allow future users to easily keep the radar relevant as threats evolve in the future.

“That capability allows them to not have to send back the system for us to upgrade the hardware for them to defend against new threats,” she said. “We update the software and push it to the radar, and they can meet the missions that they have.”

The TPY-4 is also a multi-mission radar able to track targets from 6 degrees below its position all the way up to 90 degrees and eliminate blind spots, according to the company. Its sensors can detect smaller, hard-to-identify threats through heavy clutter — other signals in the environment caused by animals, water and more.

Lockheed Martin’s contract with the Air Force includes options for the production and fielding of 35 additional TPY-4 radars. The company is currently on order for at least two more systems, Herodes said.

In the meantime, the first radar will be sent to the company’s site in Cazenovia, New York, for 15 months of testing with the Air Force, he said. The Syracuse facility uses the site to test its entire portfolio of radars, including the TPS-77 Multi-Role Radar and the Army’s AN/TPQ-53 radar.

Located at the edge of a valley in rural Upstate New York, the test site allows Lockheed Martin to assess a radar’s ability to detect objects at various distances, elevation levels and speeds, company officials said. Staff use wind farms, radio frequency signals and aircraft flybys to simulate future operating environments.

Re: Lockheed Completes First of New Air Force Radars

does the radar cover landing situations of incoming aircraft? If so, what are the manpower technical requirements for technicians on standby for changing runways?

Re: Lockheed Completes First of New Air Force Radars

how many hrs a week does your system require a technician on standby for changes in wind direction for system to work properly
