Lockheed Martin says third quarter F-35 deliveries slowed

(Reuters) - Lockheed Martin Corp (LMT.N), the Pentagon's No. 1 weapons supplier, said a retroactive fix for insulation problems in the fuel tanks and lines of F-35 jets already in production caused deliveries to be "light" this quarter.

The comments were made on the company's third quarter earnings conference call after it reported a quarterly profit beating analysts' expectations, as sales of its Sikorsky helicopters pushed total revenue up 14.8 percent.
