US B-52 strategic bombers get new radar systems

I arrived first grenade launcher A B-52 Stratofortress for the US Air Force to San Antonio. To carry out upgrades as part of the Radar Modernization Program.

American strategic bomber B-52 You will receive an Active Electronic Scanned Matrix (AESA) system. As part of the Air Force’s B-52 radar modernization program.

In addition to increased situational awareness and the ability to navigate and target, the AESA to be adaptable. So that new capabilities can be added to counter future threats through software modifications.

Boeing and Raytheon are both heavily involved in the installation process.

“Boeing is the original equipment manufacturer (OEM) of the B-52, so their long history and platform knowledge is critical. To make sure we can get out [AESA] as soon as possible”.

The company said, through its account on the Twitter platform, that the plane will depart with more accurate navigation, and improved targeting and tracking. and new high-resolution mapping and the ability to engage multiple targets simultaneously.

radar The AESA matrix

The AESA installation is one of the aircraft’s biggest upgrades B-52 in the history of the fleet. The effort will cost about $2.8 billion. With initial operational capacity expected in 2027.

The new radar is considered an enabler for the long-range confrontation capability and will prepare the aircraft for optimal lethality.”

An active electronically scanned array (AESA) is a type of phased array antenna, which is an array. It is controlled by a computer in which the beam of radio waves can be directed electronically to signal in different directions without moving the antenna.

and in AESA Each antenna element is connected to a small solid-state transceiver module (TRM) under computer control. Which performs the functions of the transmitter and / or receiver of the antenna.

This contrasts with negative electronically scanned array (PESA), where all antenna elements are connected to a transmitter. and/or a single receiver through phase shifters, under computer control. And the main use of AESA It is in the radar, known as active phased array radar (APAR).

AESA

It is the more advanced and advanced second generation of the original PESA progressive array technology. PESAs can emit only one beam of radio waves at one frequency at a time.

PESA must use a Butler array if multiple beams are needed. AESA can radiate multiple beams of radio waves at multiple frequencies simultaneously.

and can toRadars AESA can spread its emissions over a wider range of frequencies, making it more difficult to detect them through background noise. This allows ships and aircraft to radiate powerful radar signals while still being disguised. It is also more resistant to distortion.

Hybrids of AESA and PESA can also be found, which consist of matrices subtypes that are individually similar to PESA. Where each array has its own RF front end.

With a hybrid approach, the benefits of AESA (for example, several independent packages) can be achieved at a lower cost compared to pure AESA.

Boeing plane B-52 The Stratofortress is an American long-range, subsonic, jet-powered strategic bomber. It has been operated by the United States Air Force (USAF) since the 1950s.

and can afford The launcher up to 70,000 lb (32,000 kg) in armament, and has a typical combat range of about 8,800 miles. (14,200 km) without air refueling.

The B-52 design evolved from airplane Straight-wing six turboprop engines led to the final prototype YB-52 with eight engines. Jet and wings.

The B-52 made its first flight in April 1952. It was built to carry nuclear weapons for deterrence missions in the Cold War. The B-52 Stratofortress replaced the Convair B-36 Peacemaker.

Armament

Added the ability to carry up to 20 nuclear missiles AGM-69 SRAM to the G and H models, starting in 1971. To further improve their offensive capability, air-launched cruise missiles were fitted.

After testing both cruise missile Boeing AGM-86 Air Launched USAF and Navy-supported General Dynamics AGM-109 Tomahawk. The AGM-86B was selected for operation by the B-52.

A total of 194 B-52Gs and Hs have been modified to carry AGM-86s, carrying 12 missiles on the lower pylons, with 82 B-52Hs modified to carry eight more missiles on the lower pylons. launcher Swivel installed in the bomb compartment.

B-52Gs armed with cruise missiles have also been modified with distinctive wing-root fairings. Since all B-52Hs were assumed to be modified, no visual modification was required for these aircraft.

In 1990, he entered cruise missile Stealth AGM-129 ACM Service. Although it was intended to replace the AGM-86, the high cost and the end of the Cold War resulted in only 450 being produced; Unlike the AGM-86. And no conventional non-nuclear version has been built.

The B-52 was to be modified to use Northrop Grumman’s AGM-137 TSSAM as a weapon. However, the missile was canceled due to development costs.
