Saudi F-15, refueling
(click to view full)

On Nov 14/06, a US Defense Security Cooperation Agency (DSCA) notice hinted that Saudi Arabia was about to become the first F-15 operator to switch its Pratt & Whitney F100 jet engines for General Electric’s F110. There’s often a long delay between the DSCA announcement and a contract, however, let alone delivery.

The GE F110 was developed as an engine alternative to Pratt & Whitney’s original F100, and has since become very popular in F-16s due to its higher thrust. Most of the USAF’s current F-16 fleet currently flies with GE F110 engines, for instance. Despite extensive US F-15E trials in 1999, however, almost all F-15s worldwide use the P&W F100 engine. South Korea’s new F-15Ks and Singapore’s new F-15SG Strike Eagles will fly with the F110 as pre-installed equipment, becoming the first F-15 fleets to do so.

Saudi Arabia’s F-15S variant did become the first fleet to perform a re-engining switch… and the engine order is now complete.

Saudi F-15

The Saudi F-15S is an F-15E Strike Eagle variant with downgraded avionics, downgraded LANTIRN night viewing and targeting pods, and a simplified Hughes APG-70 radar without computerised radar mapping. It serves beside F-15C/D air superiority fighters in the Royal Saudi Air Force. Each fighter has 2 engines, and any purchases must also account for inventory spares. Foreign Military Sales from the USA are typically managed by a US military agency, working on the customer’s behalf.

Sept 9/08: The Royal Saudi Air Force (RSAF) has ordered 91 F110-GE-129C engines to re-engine 41 more F-15S aircraft. This order follows the Oct 3/07 order of 65 F110 engines, and the combined value of the 2 Royal Saudi orders exceeds $750 million for 156 engines, which will re-engine 70 aircraft while leaving spares in inventory. Engine deliveries will begin later in 2008. GE release.

The original DSCA request covered 155 F110 engines and associated support services, with a expected maximum of $1.5 billion.

July 24/08: Don’t forget the training. The USAF is modifying a cost plus fixed fee contract with Battelle Memorial Institute of Columbus, OH by an estimated $18.5 million. BMI will modify Royal Saudi Air Force F-15S aircraft maintenance trainers and integrated avionics trainers to add training related to the new GE engines. At this time all funds have been obligated. 558 ACSG/PK at Hill AFB, Utah manages this FMS contract (FA8223-08-C-0006).

Jan 14/08: the US DSCA announces the Government of Saudi Arabia’s official request for 900 Joint Direct Attack Munition (JDAM) tail kits that turn ordinary bombs into GPS-guided smart bombs. The estimated cost is $123 million, and Boeing would be the prime contractor.

The JDAMs are specifically noted as being “for use on RSAF F-15S aircraft”; its Tornado GR4 fleet would also present a logical set of candidates, but JDAM requires a MIL-STD-1760 data bus. The deal becomes controversial, however, and gets hung up. See “Saudi Arabia Requests JDAMs” for full details.

Dec 7/07: The US Defense Security Cooperation Agency announces Saudi Arabia’s request for 40 of Lockheed Martin’s AN/AAQ-33 SNIPER Advanced Targeting Pods, which would replace the older LANTIRN twin-pod systems installed on Saudi F-15S Strike Eagles. Sniper ATP pods significantly enhance an aircraft’s strike capability by adding stabilized long-range laser tracking and targeting illumination, high performance day/night surveillance, GPS targeting capabilities, and even some air-air target detection and tracking abilities to aircraft using them.

Note that a DSCA request is not a contract. See “Saudis Seek Sniper ATP Supplementation for F-15S” for more.

Oct 3/07: GE announces that the Royal Saudi Air Force has selected General Electric Company’s F110 fighter engine to begin to re-engine its twin-engine Boeing F-15S aircraft.

The initial agreement calls for the purchase of 65 of GE’s F110-GE-129C engines, plus a logistic support package. This will re-engine 29 aircraft, while also providing spares. Deliveries begin in 2008, and the entire package has a total value of more than $300 million.

The F110-GE-129 engine model that will power the Royal Saudi aircraft incorporates GE’s Service Life Extension (SLEP) hardware, which includes the core of a successful CFM56 commercial engine, 3D aero technology, and upgrades to the combustor and high-pressure turbine. The enhancements reportedly provide up to a 25% improvement in cost-per-flying hour, a significant on-wing increase, and elimination of special inspections. GEAE release.

Nov 14/06: The DSCA release makes Saudi Arabia’s original request, with a total value of up to $1.5 billion. The release states that this purchase “will help overcome an ongoing sustainment problem with RSAF’s F-15S engines that has affected their air operations. The RSAF is considering re-engining its 70 F-15S aircraft [DID: of the original 72], or undertaking a massive recovery/re-sustainment plan of the current engines, or a combination of both.”

The purchase will involve aircraft integration, program management, publications, trainers; mission planning, training, spare and repair parts, repair and return services, contractor technical assistance and other related elements of logistics support, plus either:

• 155 General Electric (GE) F110-GE129 engines; or

• 20 Pratt &Whitney F100-PW229 engines to restore/refurbish the Royal Saudi Air Force (RSAF) current inventory of P&W engines; support equipment; engine improvement program services; flight tests; Technical Coordination Group/International Engine Management; Hush House refurbishment; et. al.

The prime contractor will be General Electric Corporation of Fairfield, CT and/or Pratt and Whitney of East Hartford, CT.

There are no known offset agreements proposed in connection with this potential sale, and implementation of this proposed sale will potentially require the assignment of up to 10 U.S. Government representatives and up to 10 contractor representatives to Saudi Arabia for approximately one week, semi-annually, in order to participate in program support and technical reviews. Implementation of this sale also will potentially require the assignment of several U.S. Government Quality Assurance Teams to Saudi Arabia for two weeks to assist in the delivery and deployment of the engines. There may also be approximately 15 contractors in Saudi Arabia providing technical assistance on a full time basis.
