F-35 Engine Cost Update

Here’s some data on the F-35 engine cost. 

“United Technologies Corp., Pratt & Whitney Military Engines, East Hartford, Connecticut, is being awarded a $1,038,074,689 modification to the previously awarded advance acquisition contract for the Lot IX low-rate initial production F-35 Lightning II Propulsion contract (N00019-14-C-0004) for the Air Force, Navy/Marine Corps, international partners and foreign military sales (FMS) customers.  This modification provides for components, parts and materials associated with the procurement of 28 F135-PW-100 conventional take-off and landing propulsion systems for the Air Force; six F135-PW-600 propulsion systems for the Marine Corps; and four F135-PW-100 propulsion systems for the Navy.  In addition, this modification provides for seven each F135-PW-100 and F135-PW-600 propulsion systems for international partners, as well as 11 F135-PW-100 spare propulsion systems for FMS customers. This modification further provides for three spare propulsion systems and one trainer propulsion system for the Air Force.” 

That adds up to,

50 F135-PW-100 conventional take-off and landing propulsion systems

13 F135-PW-600 propulsion systems for the Marine Corps

3 spare propulsion systems

1 trainer propulsion system for the Air Force.  

The total is 67 engines at a cost of a little over $1B.  That’s a price of $15.5M per engine.

The announcement says that this is a modification to a previously awarded contract.  It’s unclear from the announcement whether this is additional money added to the previous contract or a stand alone purchase for this price.  Thus, the minimum cost is $15.5M and it may be higher.  I’m not sure how to interpret this.

Some more contract history.

“In October 2013, the U.S. Department of Defense (DoD) awarded a $1.1 billion contract to Pratt & Whitney for the sixth lot of F135 engines. The contract was for 38 engines, including 18 F135-PW-100 engines for the F-35A, seven F135-PW-400 engines for the F-35C, and six F135-PW-600 engines for the F-35B. On October 14, 2014, the DoD awarded Pratt & Whitney a $943 million contract for the seventh lot of engines (36 units).” (1)

So, that’s $28.9M apiece for 38 Lot 6 engines and $26.2M for 36 Lot 7 engines.
