Gulfstream Delivers Conformal Airborne Early Warning (CAEW) G550 Aircraft to Israeli Ministry of Defense

SAVANNAH, Ga. --- Gulfstream Aerospace Corp. yesterday delivered its first Conformal Airborne Early Warning (CAEW) special-mission aircraft to the Israeli Ministry of Defense (IMOD). In 2003, the large-cabin, ultra-long-range Gulfstream G550 aircraft was chosen as the platform for IMOD’s Airborne Early Warning surveillance system because of the aircraft’s overall performance, safety, reliability and low operating cost.

“The G550’s exceptionally long range enables it to remain on station for extended periods – a critical requirement for military surveillance missions,” said Pres Henne, senior vice president, programs, engineering and test, Gulfstream. “Also, compared to earlier surveillance aircraft, the G550 offers considerably greater operating efficiencies, yielding exceptional capabilities at much lower total cost.”

Following the aircraft’s delivery to IMOD in Tel Aviv, Israel , ELTA Systems will provide and install state-of-the-art electronic equipment. ELTA Systems Ltd. is a wholly owned subsidiary of Israel Aircraft Industries (IAI).

The CAEW aircraft features the most extensive modifications on a Gulfstream aircraft to date and like the Gulfstream V (GV) Special Electronic Mission Aircraft (SEMA) – the first of which Gulfstream delivered to IMOD last year – the modifications to the CAEW G550 platform were developed entirely by Gulfstream engineers. Using state-of-the-art design tools, including a full Computer Aided Three-dimensional Interactive Application (CATIA) electronic mockup and computational fluid dynamics to ensure high efficiency and low drag, the CAEW platform is equal in capability to aircrafts that weigh twice as much.

During development of the CAEW platform, Gulfstream originated significant increases in the baseline aircraft capability, all of which will be approved by the Federal Aviation Administration by the end of this year. To accommodate the weight of ELTA’s mission-essential equipment, Gulfstream increased the G550’s maximum zero fuel weight using a Mid-Wing Fuel Ejector that pumps fuel from the inboard side of the wing and redistributes it to the outboard fuel cells, resulting in reduced wing loads at the fuselage. This modification is available to current in-service GV, G500 and G550 business-jet operators who require additional payload capacity.

To power the extensive electronics, Gulfstream installed two additional generators – one to each of the two G550 Rolls-Royce BR710 engines. As a result, the CAEW now delivers three times the electrical power of a standard G550 business jet. To compliment the electrical power increase, Gulfstream developed a low-drag liquid cooling system that provides the optimum environment for the onboard electronic equipment. Additionally, a mission control room and a number of on-board mission operator stations were designed by Gulfstream.

“For all practical purposes, we’ve provided ELTA a ‘plug-and-play’ special mission platform,” Henne added.

BEDEK Aviation Group, also a division of IAI, is providing maintenance and integrated logistic support for both CAEW and SEMA aircraft.

Gulfstream aircraft are deployed in a number of special-mission roles including maritime surveillance; high-altitude research; weather system monitoring; medical evacuation; special electronic mission and airborne early-warning roles. More than 34 governments operate Gulfstream aircraft, including some 22 that use the jets for head of state transport.

The large cabin, ultra-long range G550 business jet was introduced in September 2002. It can reach speeds up to Mach .885, cruise as high as 51,000 feet, and has a range of 6,750 miles. It features the PlaneView flight deck and the award-winning Gulfstream Enhanced Vision System. The G550 features a cabin volume of 1,669 cubic feet, with an additional 226 cubic feet of baggage space available; a maximum cabin altitude of 6,000 feet; 100 percent fresh air in the cabin; and 14 large oval windows that allow for a generous amount of natural light.

Gulfstream Aerospace Corporation, a wholly owned subsidiary of General Dynamics, designs, develops, manufactures, markets, services and supports the world’s most technologically advanced business-jet aircraft. Gulfstream has produced more than 1,500 aircraft for customers around the world since 1958. The company employs more than 7,900 people at seven major locations. (ends)

First Compact Airborne Early Warning G550 Landed Yesterday in Israel

A Gulfsteam G550 aircraft arrived in Israel yesterday (19 September 2006) and was accepted by the Israel Air Force. The aircraft will be now turned over to Israel Aircraft Industries' Elta Systems Group and Subsidiary for the installation of a new generation Conformal Airborne Early Warning (CAEW) system.

Elta Systems is the prime contractor, system developer and system integrator on this program for the Israel Air Force.

When Elta's systems are installed, the completed aircraft will be one of the most advanced Airborne Early Warning aircraft in the world. The CAEW system will be used for intelligence gathering and air combat command and control missions.

Prior to delivery to the Israel Air Force, the aircraft was modified by Gulfstream to all the electronic equipment. The modified G550 then underwent a series of flight tests in the United States to verify in-flight performance and airworthiness.

Israel Air Force Commander, Maj. Gen. Elyezer Shkedy (photo – left side) said yesterday at the ceremony: "The new aircraft will utilize advanced radar systems made by IAI/Elta and will play a substantial role in displaying aerial information. Its capabilities are beyond what we have today".

Elta Systems' President, Mr. Nissim Hadas (photo – right side) explained the aircraft's characteristics and said: "Installing an advanced AEW system on such a compact aircraft is a tremendous engineering challenge. It is a great advantage to the air force, since this aircraft will provide better capabilities with lower operational and maintenance costs. Elta will continue to support the Israel Air Force and provide it the most advanced technologies."

Special features of the Elta CAEW system and aircraft are:

- Two radar systems which operate simultaneously in different frequency bands.
- Full 360 degrees detection capability.
- Advanced signal processors that allow very high detection ability.
- Unique system architecture that allows adaptation of all communication suites.
- High altitude flight profile that insures detection of low flying targets at very long ranges.
- Very low operational and maintenance costs.

The Israel Air Force G550 Conformal Airborne Early Warning aircraft will comprise the third generation early warning system that was developed by Elta starting in the mid 1980s.

Elta and Israel Air Force studies showed that a business jet such as Gulfstream G550 is a more efficient and cost-effective platform than large airline-type aircraft.

Israel Aircraft Industries is a recognized leader in the aerospace and defense industry and Israel’s largest industrial exporter. Elta Systems, a Group and a wholly owned Subsidiary of IAI, is one of Israel's leading defense electronics companies and a leader in Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR), Early Warning and Control, Home-Land Security (HLS), Self-Protection and Self-Defense and Fire Control applications. Elta's annual sales reach approximately $700 million with 3000 employees.
