In this video, Motley Fool industrials analyst Blake Bos reviews the important issues for both Lockheed Martin and Boeing. For Lockheed, the ongoing problems with its F-35 fighter jet will hamper orders and earnings. The company needs to establish and validate a cost per hour figure before customers start placing orders. For Boeing, look for development of its 777X passenger aircraft and how contracts are progressing. The aircraft won't go into production until 2019 or so, but Boeing will start taking orders well before then. One key selling point: a 10% improvement in fuel efficiency. Also, the 737 MAX will be rolling out with a new engine designed for a 15% improvement in fuel efficiency. This new engine should be thoroughly tested and ready to roll on one of Boeing's most successful aircraft.
