Pretty amazing schedule.  If the government were doing it, it would take $3 billion and six years for the prototype to fly.

Their website doesn't include any design info; but the Canton paper says: 

"The new airships will be about 50 feet longer than the current 192-foot blimps and fly at a speed of 73 mph, compared with the current speed of 54 mph.

Each new airship is expected to cost about $21 million, including technical support. They also will have state-of-the-art avionics and flight-control systems.

An internal frame is one of the features that will separate the new aircraft from the current blimps. The new semi-rigid airships will still be called Goodyear blimps even though Ogden says purists would point out that blimps do not have internal frames. They basically are large, helium-filled bags with gondolas, or cabins, fastened underneath for the pilot and passengers.

The new blimps also will have three prop-engines instead of two, with two engines on the side of the airship and one at the rear."
