Saudis Seek E-3 Fleet Upgrades
The 707-based E-3 aircraft forms the backbone of American, British, French, and NATO airborne early warning and control (AWACS), monitoring large swathes of airspace from an elevated position to detect incursions by enemy fighters, missiles, and even UAVs. When coupled with communications systems that allow it act as an airborne relay and command post for the aerial fight, it becomes a uniquely valuable weapons system. Under the 1981 – 1986 “Peace Sentinel” program, Saudi Arabia bought 5 E-3 AWACS(Airborne Early Warning and Control) planes and 8 KE-3A aerial tanker and cargo aircraft. Up to 3 of the KE-3s were later converted to RE-3A TASS(Tactical Airborne Surveillance System) electronic eavesdropping planes, leaving 5 E-3As, 3 RE-3As, and 5 KE-3 tankers.
Most E-3s around the world are well over 20 years old, and American, British, French, and NATO aircraft have received ongoing upgrades. Like Boeing’s US, British, French, and NATO customers, the Saudis are now seeking upgrades to keep their aircraft up to date. Broadly speaking, Saudi jets are getting 3 kinds of upgrades.
Saudi E-3 Upgrades
The 1st set of upgrades is the most basic, and the most necessary. Saudi E-3 avionics need to be upgraded, in order to comply with international aviation rules. Those are often referred to as CNS/ATM (Communications & Navigation Systems/ Air Traffic Management) upgrades.
A 2nd kind of upgrades involves military communications, which can be improved by adding high-bandwidth transmissions, and better transmission security. The RSAF’s E-3As and RE-3As have no peers among the Gulf Cooperation Council states, and integration that let them work with the UAE’s new command and control infrastructure would create a powerful regional resource. The parties involved aren’t discussing that aspect.
The 3rd kind of upgrade involves surveillance electronics. Radar System Improvement Program (RSIP) kit upgrades improve the AWACS radar by boosting its sensitivity, toughening it against jamming, and improving its reliability. Related enhancements to the plane’s passive listening electronic support measures (ESM) system can help the plane detect, identify and track electronic transmissions from ground, airborne and maritime sources, in order to determine radar and weapons system types within its surveillance range.
Contracts & Key Events
Work will be performed in Riyadh, Saudi Arabia (50%), Seattle, WA (30%); and Baltimore, MD (20%). Work is to be complete by June 15/15. ESC/HBSK, Hanscom Air Force Base, Mass., is the contracting activity (F19628-01-D-0016, Delivery Order 0080).
Dec 14/11: Installation. Boeing in Seattle, WA received a $50.4 million firm-fixed-price, cost-plus-fixed-fee, time-and-material contract for installation and check out of Group A and B RSIP kits in the Saudi fleet of 5 E-3s. Work will be performed in Seattle, WA, and is expected to be complete in Oct 28/13. This was a sole-source acquisition, managed by the ESC/HBSK at Hanscom AFB on behalf of their Saudi client (F19628-01-D-0016, Delivery Order 0080).
2008 – 2010
Aug 20/10: Northrop Grumman Electronic Systems in Baltimore, MD receives a $9.8 million contract which will replace narrow band klystron power amplifiers with wide band klystron power amplifiers in Saudi Arabian and French E-3 AWACS fleets.

The principal contractor will be L-3 Communications Integrated Systems Company in Greenville, TX. Implementation of this sale will involve up to 6 U.S. government and four contractor personnel to participate in program reviews at the contractor’s facility every 6 months. There will be approximately 6 contractors in Saudi Arabia providing technical assistance on a full-time basis until the system is integrated into the operational units.
Aug 7/08: Boeing in Kent, WA received an indefinite delivery/indefinite quantity, fixed-price delivery order contract not to exceed $42 million. In return, they will install the Radar System Improvement Program (RSIP) capability on 5 Royal Saudi Air Force AWACS jets. At this time $27.3 million has been committed. 551 ELSG/PKS at Hanscom AFB, MA manages the contract (F19628-01-D-0016, #0062).
This first phase includes a study to determine which parts are obsolete and no longer available, then locating and testing parts obtained from new sources. Phase one also includes purchase of many long lead parts and the start of software design. The next phase involves production and installation of the Radar System Improvement Program (RSIP) kits, software integration and testing, and crew training. Phase 2 was intended to be part of a 2009 follow-on contract, but actually arrived in June 2010.
The RSIP kit is built principally by Baltimore-based Northrop Grumman Electronic Systems under subcontract to Boeing. It consists of a new radar computer, a radar-control maintenance panel, and software upgrades to the radar and mission-system programs. Boeing release.
2001 – 2007
Feb 28/07: Ongoing maintenance is also part of the US-Saudi AWACS relationship. The RSAF’s 6th Flying Wing brings an E-3A aircraft to Tinker AFB, OK for repairs, and the 566th Aircraft Maintenance Squadron’s E-3 Maintenance Flight replaces a bearing between the rotodome and aircraft. A 6th Wing aircrew will perform aerial tests before returning the aircraft back to the Kingdom of Saudi Arabia. Tinker AFB, OK sustains the RSAF Peace Sentinel fleet (E-3A and KE-3A aircraft) through a Letter of Offer and Acceptance and the 557th Aircraft Sustainment Squadron’s Mid East Support. USAF release.
Dec 7/07: RSIP request. The US Defense Security Cooperation Agency announced [PDF] Saudi Arabia’s official request for 5 sets of Airborne Early Warning (AEW) and Command, Control and Communications (C3) mission equipment/Radar System Improvement Program (RSIP) Group B kits for subsequent installation and checkout in all 5 of its E-3A Airborne Warning and Control Systems (AWACS). In addition, this proposed sale will include spare and repair parts, support equipment, publications and technical documentation, contractor engineering and technical support, and other related elements of program support. The estimated cost is $400 million, and the prime contractor will be Boeing Aerospace Company in Seattle, WA.
Implementation of this proposed sale will require the assignment of approximately four contractor representatives to Saudi Arabia to provide technical assistance to integrate the aircraft into the operational units. Also, this program will require U.S. government and contractor personnel to conduct annual, one-week Program Management Reviews in Saudi Arabia. The DSCA adds that:
“Saudi Arabia needs this additional mission equipment to continue its development of an extended Airborne Early Warning (AEW) capability, as well as enhanced command, control and communications (C3).”
While other Saudi weapon requests are drawing fire, the E-3 program is unlikely to find itself caught in that vortex due to the routine nature of the request, its non-offensive nature, and the value to the US of having additional AWACS surveillance assets to maintain key “orbits” in the region.
Nov 13/06: Link 16. Saudi Arabia purchases JTIDS Link 16 systems, which quietly transmit a shared picture to participating aircraft and ground stations. A contract to install them in the RSAF’s E-3 AWACS fleet was issued in September 2007. See “Link 16 for Saudi E-3 AWACS” for full details.
August 2001: Hardware & displays. Boeing began installing new mission computers and other hardware and software on the Royal Saudi Air Force (RSAF) AWACS fleet, as part of a contract worth $60 million. Under the contract, Boeing upgraded the aircraft’s mission computer and software to the same level currently in use by the U.S. AWACS fleet and train Royal Saudi Air Force operators. That project was completed in 2003.
