The U.S. Navy's SES-100B 100-ton Surface Effect Ship streaks past a Navy observation craft at more than 80 knots (92 miles per hour) as it establishes a world speed record for this type of air-supported vessel.

The U.S. Navy's SES-100B Surface Effect

Ship test craft has achieved a speed in excess of 80 knots (92 miles per hour)—a world rec- ord for this type of vessel.

Textron's Bell Aerospace Division of New

Orleans, La., which developed and now is testing the 100-ton propeller-driven air-sup- ported craft for the Naval Material Command's

Surface Effect Ships Project Office (PM-17), set the world speed record for this type craft during a test mission at Panama City, Fla., on April 16, 1974.

Prior to the high-speed run, Dr. David S.

Potter, Assistant Secretary of the Nivy for

Research and Development, had participated in a test mission in the Gulf of Mexico and had operated the SES-100B for 30 minutes at speeds of more than 60 knots. •The record speed was accomplished during tests on an instrumented range, and the speed was recorded by highly-precise tracking radar operated by U.S. Naval personnel.

A six-man Bell Aerospace/Navy crew was on board the SES-100B for the high-speed test mission. Capt. Gordon H. MacLane, USCG (ret.), Bell's craft commander, was at the con- trols. Other crew members were Lt. Robert

Hartman, USN, Navy craft commander;

Charles E. Lester, first officer; Alvin T. Thaw- ley, test director, John. S. Wakefield, data ac- quisition engineer, and Frank L. Richter III, chief of the boat.

The crew described the craft's stability as "excellent" and said they had a smooth ride throughout the high-speed operation. Bell

Aerospace engineers reported that the craft performed flawlessly. They said the speed achieved was extremely close to predictions based upon analysis and model test data.

The record speed run followed the success- ful completion of testing necessary to confirm the technology for the design of a 2,000-ton oceangoing Surface Effect Ship. During mis- sions in the Gulf of Mexico, the SES-100B Has operated for considerable periods of time in high-sea states, and has repeatedly demonstrat- ed performance, stability and hahitaibility ex- ceeding expectations.

In addition, the Bell-developed SES-100B was the first Surface Effect Ship to expand its operating envelope to more than 70 knots (82 miles per hour). This milestone took place in testing on Louisiana's Lake Pontchartrain more than a year ago.

The extensive technical data being generated by the heavily instrumented SES-100B is being used by the Navy and Bell Aerospace" to vali- date the predictions and design features to be incorporated into larger Surface Effect Ships in the 2,000-ton class.

The SES-100B, almost 78 feet long with a beam of 35 feet and weighing a little more than 100 tons, rides on a drag-reducing cushion of air contained by catamaran-style side hulls and flexible bow and stern seals.

The air cushion is generated by eight lift fans driven by three marine ga!S turbine en- gines. When cruising, the center portion of the hull is clear of the water and the craft sup- ported almost entirely by the air cushion with only the lower surface of the catamaran side hulls skimming the surface for stability and propulsion.

Propulsion for the craft is provided by three marine gas turbines which drive two semi sub- merged, controllable pitch, supercavitating pro- pellers.

Financial Aid Sought To Build $65-Million Worth Of Offshore

Drilling Rigs, Tugs And Barges

Applications have been filed with the Mari- time Administration for Government backing of more than $65-jmillion worth of offshore drilling units, barges, and tugs.

Meanwhile, MarAd approved construction loan and mortgage insurance under Title XI of the 1936 Merchant Marine Act for the $14- million reconstruction of a World War II-built

CL-M^AVl into a self-propelled drilling rig for Storm Drilling Co. of Houston, Texas, for use in the Gulf of Mexico and foreign waters.

Bethlehem Steel Corporation of Beaumont,

Texas, will do the work.

The applicants for such financial aid are: — Atwood Oceanics 'Inc., Houston—two self-elevating platform (jackup) drilling units estimated to cost $39.4 million, with construc- tion to be done by Marathon LeTourneau,

Brownsville, Texas and Vicksburg, Tenn. The units are to be used in offshore exploration. — L&L Marine Service Inc., Clayton, Mo.— two oceangoing tugs at a total of $4.6 million and four barges of $4.5 million to be char- tered to Union Carbide Corp. for Gttlf-Puerto

Rican movements of petroleum coke and elec- trode binder pitch. Lamont Shipbuilding &

Repair Co., Lamont, 111., will do the building. — Hannah Barge 5101 Partnership, Lamont, .111.— one double-skinned petroleum barge of 51,(MX)-!barrel capacity, estimated to cost $2.6 million. The builder of the Great Lakes barge will be DeFoe Shipbuilding Co., Bay City,
