We are adding four more photos today from the Flight Test Museum at Edwards Air Force Base — F7F-3 (N7195C). It was operated by Sis-Q Flying Service as Tanker 32 in May, 1973, and as Tanker 40 in August, 1975.
The Grumman F7F Tigercat is a heavy fighter aircraft that served with the United States Navy (USN) and United States Marine Corps (USMC) from late in World War II until 1954. It was the first twin-engine fighter to be deployed by the USN. While the Tigercat was delivered too late to see combat in World War II, it saw action as a night fighter and attack aircraft during the Korean War. Armament was heavy: four 20 mm cannon and four 50 caliber (0.50 in; 12.7 mm) machine guns, as well as underwing and under-fuselage hardpoints for bombs and torpedoes.
The F7F-3 Tigercat variant:
Single-seat fighter-bomber aircraft, powered by two Pratt & Whitney R-2800-34W radial piston engines and featuring an enlarged tail fin for improved stability at high altitudes, 189 built.
Beginning in 1949, F7Fs were flown to the then-U.S. Navy storage facility at Naval Air Station Litchfield Park, Arizona. Although the vast majority of the airframes were eventually scrapped, a number of examples were purchased as surplus. The surviving Tigercats were primarily used as water bombers to fight wildfires in the 1960s and 1970s and Sis-Q Flying Services of Santa Rosa, California, operated an F7F-3N tanker in this role until retirement in the late 1980s.
The Pratt & Whitney R-2800 (US military designation) Double Wasp (civil designation) is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 in³ (46 L), and is part of the long-lived Wasp family.
The R-2800 saw widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade the engine, including water injection for takeoff in cargo and passenger planes and to give emergency power in combat.
These photos were taken by Bob Martinez, a Volunteer in Prevention Photographer with CAL FIRE. They were taken on the Goose Fire near Prather, California, about 18 miles northeast of Fresno. Thanks Bob!
The Goose Fire has burned 2,241 acres and 4 homes and is approaching containment.
Three more of Neptune’s BAe-146 air tankers are being brought into the current fleet. Tom Harbour, Director of Fire and Aviation Management for the U.S. Forest Service, confirmed today at the Large Fire Conference in Missoula that two BAe-146s came on in the last few days and a third will be on board by June 1.
The three aircraft are being added to Neptune’s “legacy” air tanker contract using the “additional equipment” provision.
These three air tankers are being added to the fleet along with the two additional DC-10s that were announced last week. 10 Tanker Air Carrier had one DC-10 already working on a next-gen contract and a second was converted last week from a call when needed contract to exclusive use, using the additional equipment provision on their contract. 10 Tanker is converting a third DC-10 that will also be on the next gen exclusive use contract when it is complete this summer.
Neptune Aviation assembled their five BAe-146 air tankers on the tarmac at Missoula for picture day. It is a pretty remarkable photo — five jet-powered air tankers that meet the basic U.S. Forest Service criteria to qualify as “next-generation” air tankers, which require the aircraft to be turbine or turbofan (jet) powered, be able to cruise at 300 knots (345 mph), and have a retardant capacity of at least 3,000 gallons.
Only one of these five air tankers has a confirmed contract with the federal government, the USFS. It is on a “legacy” contract. Neptune Aviation has three additional BAe-146s that are ready to fly now, and one more will be complete sometime this summer. The USFS is still dithering about what to do after the Government Accountability Office upheld the protest of a contract that was given to Neptune without competition for two BAe-146s. About the only options available now for the USFS are to add some of the BAe-146s to the legacy contract as additional equipment, ignore the GAO decision and honor the no-competition contract, or cancel the no-competition contract and do nothing about the other four Neptune BAe-146s that are sitting on the ramp at Missoula.
A very unlikely option would be for the USFS to allow competitive bidding on an additional contract. All of the existing valid legacy and next-gen contracts allow for up to four additional aircraft to be added as “additional equipment” to each line item. The vendors that won the awards for those contracts are all hoping to add more aircraft down the road, and would most likely be very distressed if another company came in that lost competitive bidding previously, and basically took away their opportunity to supply more air tankers.
But, it is painful to see four recently retrofitted, freshly painted, jet air tankers sitting on the tarmac — with a rather bleak future.
