The aircraft builder is working with Alaskans and is close to finishing deals to help make that happen, said Craig Johnston, director of business strategy and development for a California-based Lockheed Martin program, Skunk Works, that is developing a helium-filled airship.

Lawmakers on the House Energy Committee who heard Johnston's presentation said the ships could play a big role in Alaska, economically hauling freight and workers to remote sites.

Advocates say the airships eliminate the need for costly roads and runways, making them perfect for delivering supplies across large swaths of Alaska without highways. The ships will be able to carry large loads and land at isolated clearings such as snowfields, ponds and frozen lakes, they say.
