> According to Wikipedia the $90 million is without an engine, which is just weird.

Yes, a plane without engines is just a pretty mockup that sits on the ground. But, from Lockheed Martin's perspective, the engine is government furnished equipment. LM does not build engines. The government has a totally separate contract with Pratt & Whitney for the development and production of F-135 engines, and another separate contract with Rolls Royce for the development and production of the LiftSystem in the F-35B.

This is why the costs are given as "without engine". Because the engine is a separate contract.
