FOUR BIDS MADE ON NAVY AIRSHIPS

——-

     Lowest is $29,876 and Highest $200,000 for Construction of Dirigibles.

     Washington, April 20. – Four firms to-day competed in the bidding for the construction of the first dirigible airships for the United States navy.  The bids disclosed a wide divergence.  The lowest was $29,876, or $58,552 for two dirigibles, while the highest was $200,000 for a single aircraft.

     The dirigible will be neither impressive or large.  Their principal function will be to furnish training for pilots and to serve as a basis for investigation of the workability of dirigibles in maneuvers.  The Secretary of the Navy’s memorandum issued today said:

     “The Office of Aeronautics considers that the dirigible is to be the kingfisher of the submarine.  The aeroplane, rapidly scouting the seas off our harbors and around our fleet, discovers the enemy’s submarines lying in wait for innocent merchant ships, or attempting to creep up on our fighting ships.”    

     “The dirigible from the shore station or from the dirigible ships of the fleet, thus warned by the aeroplane scouts, proceed to the attack of the submarines, dropping on them heavy bombs fitted with fuses to explode on hitting or after sinking to a certain depth”

     The general specifications required that the dirigibles should be of the non-rigid type, 175 feet long, 50 feet high, and 36 feet wide, with a useful load of about 2,000 pounds.  It is specified that they have a speed of twenty-five miles an hour, and be capable of rising 3,000 feet without disposing of ballast.

     The following bids were received: Stanley Yale Beach, New York – One machine, $29, 876; two machines, $58,552.  American Dirigible Balloon Syndicate, Inc., New York – One machine, $41,000; one machine (larger), $45,000.  The Connecticut Aircraft Company, New Haven – One machine, $45,636.25; two machines, $82,215.12.  The Goodyear Tire and Rubber Company, Akron, Ohio, – One machine, $200,000.

     The last bid is subject to a reduction which will make the total cost to the government equal to the cost of the machine to the Goodyear Tore and Rubber Company plus 50 per cent.

    History has shown that the contact was awarded to the Connecticut Aircraft Company.  The first dirigible ordered was designed to carry eight men, four of whom would serve as crew, and the other four as student observers.  The ship would be 175 feet long, 55 feet high, and would have a gas capacity of 110,00 cubic feet.  It could achieve a speed of 25 mph and operate for two hours in the air – longer if fewer men were aboard.

     On January 22, 1916, The Manufacturers Exhibition opened in New Haven, Connecticut.  One display that drew great interest was a model of a dirigible airship that had been constructed by the Connecticut Aircraft Company of New Haven; the first dirigible ever built for the United States Navy.    

     At the time of the exhibit, the airship was in a hangar at the Portsmouth Navy Yard in New Hampshire, undergoing some final preparations before it would sail to Pensacola, Florida, to under go trials and testing.

     The initial order for the dirigible was placed May 14, 1915.  It was reported at that time that the ship would be constructed in New York, assembled in New Haven, Connecticut, and shipped for trials to the Pensacola, Florida, Naval Aeronautic Station, all under the supervision and guidance of the Connecticut Aircraft Company.     

     The model displayed at the exhibition was designed to be towed by a battleship traveling 25 miles per hour against a 15 mph wind to be utilized by lookouts, and spotters for directing ship’s fire during battle conditions.   Traditional balloons had proved to be problematic in this roll due to their lack of stability under these conditions which often resulted in seasickness for the observers.

     The completed dirigible was described as being be 175 feet long, 50 feet tall, and 35 feet in diameter. It would carry a crew of eight, and cost $45,636. 

     The balloon was built with inner compartments that divided the front from the back, either of which could be pumped full with regular air to displace the hydrogen gas so as to make one end of the ship heavier or lighter to aid in ascending or descending.    

     Government specifications required that the dirigible be capable of rising at the rate of 8 feet per second. 

     Fabric for the balloon was manufactured at the United States Rubber Company.   

     On March 13, 1917, with the United States now involved in World War I, contracts totaling $649,250 were awarded to four manufacturers to produce 16 additional dirigibles for the U.S. Navy. 

     The awards were as follows:

     Three dirigibles to be built by the Curtis Aeroplane Company in Buffalo, N.Y., for $122,250.

     Two dirigibles to be built by the Connecticut Aircraft Company of New Haven, CT., for $84,000.

     Nine dirigibles to be built by the Goodyear Tire & Rubber Company of Akron, Ohio, for $360,000.

     Two dirigibles to be built by the B. F. Goodrich company in Akron, Ohio, for $88,000.  

     During its tenure in business, the Connecticut Aircraft Company build 177 airships and balloons of various kinds.  In 1921 the company was acquired by a Delaware corporation known as the Aircraft-Construction Corporation, and continued to produce dirigible airships under that name.
