Airfield Crash Rescue Jeeps


 

Jeeps have long been a logical part of airport fire fighting, because aircraft do not follow roads, and if they crash, even in the vicinity of an airport, it is likely to be in an off-road area. Some of these photos have appeared on other pages on the website, but I thought it made sense to assemble them in a chronological look at the technology. Footnotes to reference sources are at the bottom of the page. -- Derek Redmond

Carbon Dioxide

Carbon dioxide gas (CO2) extinguishers were developed before World War II by the Walter Kidde Company for use on burning electrical equipment. (1) They instantly deprive a fire of oxygen without scattering burning liquids such as gasoline, making them also a logical choice for rapid response to an airplane fire.

Kidde ad

This Kidde advertisement from near the end of the Second World War is an update of a 1944 version. Click the image for the full ad.

The text says: "Coast Guard airports find a new job for the versatile jeep. They've manned it with asbestos-clad fire-fighters, loaded it with Kidde carbon dioxide extinguishers. This tough little 'fire engine' can rush right up to crash-fires or other blazes, hit them hard and fast with fire-smothering carbon dioxide gas."
 

29AA92 The Coast Guard were not the only ones to equip jeeps for crash rescue during WWII. Royal Air Force Crash Jeeps were standardized in 1944, and carried two twelve-pound CO2 extinguishers as well as other gear. They were painted olive drab, with a red windshield.

Experience with aircraft fires during the war, as well as fires aboard Navy ships, would eventually lead to advances in firefighting technology.
 

Palmdale

Palmdale, 1948 This CJ-2A at Palmdale Regional Airport in northern Los Angeles County is still equipped with a CO2 extinguisher. In the background is what appears to be a WWII surplus Class 135 military crash truck.

The photo is undated, but the Jeep's yellow-on-black "Octagon E" license plate (tax-exempt plate for county-owned vehicles) would indicate 1963-1968. It's surprising that fire equipment at Palmdale was not more advanced by then, because since 1953 the airport had been the site of the U.S. Air Force's huge "Plant 42" military aircraft manufacturing facility, still active today.(2)

One event which should probably have encouraged updated fire protection at the airfield was the infamous "Battle of Palmdale" on 16 August 1956. An unmanned Grumman Hellcat, being used as a target drone for missile testing, went rogue after taking off from Palmdale. It eventually ran out of fuel and crashed in the desert, after two USAF F-89 Scorpions were scrambled but failed to shoot it down with a barrage of air-to-air missiles, which caused damage and extensive fires on the ground, but no fatalities. (3)

See also an extinguisher-equipped Calgary Airport Fire Jeep which the airport probably relied on more for response to calls from the parking garage than incidents on the flight line.

Dutch Air Force

In January 1953, the Royal Netherlands Air Force (Koninklijke Luchtmacht or "KLu") took the concept of Jeeps with CO2 extinguishers to the extreme, when they ordered 27 CJ-3As from Willys importer H.C.L. Sieberg, with modifications by P.J. Pennock & Sons in The Hague.

Netherlands LM-21-68 The KLu Jeeps carried multiple CO2 cannisters, two floodlights with 24V PTO generator and 120-ft. cables, tools including 24V power saws, and multiple cylinders of methyl bromide, a highly toxic gas used at the time as an extinguishing agent because it not only cut off the oxygen, but actually inhibited the chain reaction of burning. (1) See a rear view (160K JPEG) of the Pennock modifications.

The 3As could also pull trailers carrying eight more bottles of methyl bromide. Photos courtesy Jan Hogendoorn.
 

LM-19-72 One of the KLu CJ-3As poses here (behind the David Brown aircraft tug on the right side of the photo) as part of a 1964 display at Twente Air Base, of the necessary ground equipment and personnel to support an F-104 Starfighter -- a plane developed at Palmdale in the early 1950s. (4)

Netherlands LM-19-72 This closer view shows the Jeep in the same display, and it's still looking pretty good eleven years after delivery. It's manned by two firefighters in asbestos proximity suits.

Atlanta

AtlantaA CJ-6 at the Atlanta Airport Fire Station is a slightly later example of a Jeep with a full load of carbon dioxide cylinders. The CJ-6 made good use of its extra rear capacity compared to shorter-wheelbase Jeeps.

A mobile CO2 unit allowed very fast response, but for a fire of any significant size, backup by something like a foam truck would be needed because once the CO2 is dispersed, flames can quickly reignite.
 

Protein Foam

LM-19-72 In November 1958, LIFE (5) published this photo of "a blizzard of thick, white, fire-snuffing foam" being used on a fiery crash between two planes at New York's Idlewild Airport. See the full story of this incident, including a CJ-3B baggage loader playing a role, in Jeep Helps Out at Airport Fire on CJ3B.info.

This kind of foam is produced by mixing a soybean protein concentrate into water as it's pumped to the nozzle, and it both cools the fire and sits on top to cut off the oxygen, preventing reignition. (6)
 

Little Squirt demo One of the few experiments in putting a large foam gun on a Jeep, was conducted in the early 1950s by the U.S. Navy, who initially converted a WWII surplus jeep to carry 200 gallons of water, 20 gallons of foam concentrate, and an agitator to mix the two.

It was demonstrated to the press in October 1952. Photo by Ed Walston of the International News Photo agency.
 

Little Squirt CJ-3B The Navy then built another version of what they dubbed "Little Squirt," on a new CJ-3B. See more details and photos in U.S. Navy Crash Jeep Prototype on CJ3B.info.

Foam In another exercise, firefighters attempted to cover the new Little Squirt with foam, possibly to demonstrate that it would continue pumping under those conditions.

There were apparently hopes of selling a civilian version of the small but very heavy foam unit. This didn't happen, probably because there were alternative extinguishing agents better suited to a small vehicle, some of them also being developed by the Navy.
 

Dry Chemical and AFFF

CJ-2A This CJ-2A was converted as a crash truck for the airport at Dafoe, Saskatchewan in 1947. Later used at Yorkton and at St. Andrews Airport near Winnipeg, it was donated in 1990 to the Royal Aviation Museum of Western Canada.

There is a CO2 extinguisher on the driver's side, and an 18-pound dry chemical unit on the right fender. This type of extinguisher had been invented before the war, but was not widely used until the 1950s -- it has a smaller cylinder on the side which holds carbon dioxide to pressurize the main cannister of sodium bicarbonate (baking soda) when the seal is punctured. (7)
 

CJ-2A The passenger seat was removed to make room for a large CO2 cylinder to pressurize the rear tank, which holds probably 300 pounds of sodium bicarbonate powder, delivered through a rubber hose.

Also well worth seeing at the Royal Aviation Museum in Winnipeg is the cavernous Bristol 170 Freighter behind the Jeep (180K JPEG, photo by Cesamos for tripadvisor.ca.) Built in the UK in 1955 for the RCAF, it was later sold to Wardair and then Norcanair to carry freight in northern Canada, and was donated to the museum in 1983.

Springfield, Missouri

Springfield MO Another 1947 CJ-2A has been restored and displayed at the airport in Springfield MO. According to the plaque mounted on the front (110K JPEG) the Jeep was originally configured with a 100-gallon tank of premixed foam, delivered by a front-mounted pump. The pump has since been replaced by a Federal siren, and a pressure tank in the rear is pre-connected to 2-1/2-inch hose.
 

Springfield MO I don't know the specs of the system, or whether the hose as installed in the restoration is correct. It may be an Ansul dry chemical or AFFF system (see below) dating from the 1950s-1970s. Thanks to Ted Hutchens for these photos.

Another airport with a similar system in a Jeep (a CJ-3B) was San Francisco International, as seen in the movie Julie (1956).
 

Ansul Chemical

Islip MacArthur Airport, Long Island NY This 1953 CJ-3B, which served Islip MacArthur Airport on Long Island NY from the 1950s to the early 1970's, is an example of the popular J2-340 conversion by Ansul Chemical of Marinette, Wisconsin. It was Ansul who popularized dry chemical extinguishers, and the J2-340 carried a 300-pound sodium bicarbonate tank as well as a battery of smaller units.
 

Greensboro NC, 1962 The crash of a USAF C-47 (military DC-3) at Greensboro NC on 4 February 1962, killing all seven personnel on board, revealed the limitations of the Ansul J2-340 in dealing with a burning multi-engine aircraft. The Jeep was on the scene quickly, but its tank was exhausted before the fire could be knocked down.

For details on this incident, and lots more photos and information on what was otherwise the most successful and widely-used crash Jeep, see Ansul Chemical Crash Trucks on CJ3B.info.
 

Elko NV Ansul's solution for airports that wanted more capability but weren't ready for a large crash truck, was a trailer with the one-two punch of "Purple K" (potassium bicarbonate) powder and "Light Water" (AFFF or Aqeuous Film Forming Foam) both of which were developed in the 1960s by the U.S. Navy.

Delivered through a 100-foot double hose to twin nozzles, the dry chemical put out the fire and the Light Water film covered it to prevent re-ignition.

US Navy, 1968 In 1968, Ansul supplied the Navy with smaller Purple K / Light Water double-hose systems on skids, for mounting on small vehicles to be used on aircraft carriers. This was one of a number of changes to firefighting equipment and protocols, in response to the 1967 USS Forrestal disaster. (8)

"Light Water" was a trademark of 3M Corporation, who worked with the Navy on the development of what is now known as AFFF. Using a fog nozzle, it makes maximum use of a small tank of liquid to create a thin layer of film, and both Purple K and AFFF are still widely used for aircraft firefighting.
 

More Dry Chem Systems

France Willys MBs (or more likely M201 versions built by Hotchkiss in France) were equipped by the Gendarmerie (France's federal police) with spherical dry chemical powder tanks in the 1970's, for use at helicopter bases. The modifications were reportedly in service into the early 1990's. See also a front view (90K JPEG).

Netherlands Maastricht Aachen Airport is in the Dutch province of Limburg, at the southern tip of the Netherlands. The airport's Brandweer ("fire brigade") fielded this CJ-3B in the 1950s, and apparently weren't worried about the empty extinguisher bracket since they were pulling a couple hundred pounds of probably ABC dry chemical (monoammonium phosphate) which was in use in Europe before it was adopted in North America. (1)

"Factory" Crash Wagon

Crash wagon Willys advertised a factory-approved CJ-3B Jeep Crash Wagon in many of its special equipment catalogues and brochures in the 1950s, but I have never seen one outside of those publications. This 1958 photo appeared in the booklet Jeeps for Aircraft Ground Support.

According to a page of Specifications (190K JPEG) the Crash Wagon carries 850 cubic feet of foam and 90 pounds of carbon dioxide gas, including a hand extinguisher of each type. A 75-pound CO2 cylinder is mounted across the body just behind the front seats.
 

W-O FD In the 1955 Willys booklet Jeep Vehicles in Public Service the Crash Wagon is shown with the rear-mounted foam tank pivoted forward, so it's probably empty. This is apparently a tank of sodium bicarbonate solution, with an inner container of a chemical such as aluminum sulphate, which mixes to create expanding foam when the tank is inverted, like the soda-acid hand extinguisher.

This might account for the somewhat optimistic statement in the specs: "The equipment can be operated by inexperienced personnel, and highly trained fire-fighting crews are unnecessary."
 

Crash Wagon A catalogue of Jeep Specialized Vehicles and Equipment circa 1959 showed a CJ-5 version of the Crash Wagon, with the same equipment. (In this photo the CO2 extinguisher is shown on the passenger side.) The foam tank has a 50 ft. hose, and the CO2 cylinder has a 25 ft. hose.
 

Versatile CJ-5

1960 CJ-5 This photo from the Jeep corporate archives is a puzzle; it was shot at a Kaiser-Willys dealership, and reportedly shows a 1960 CJ-5. The Jeep appears to be configured with a dry chemical cylinder and hose on the front bumper, plus a big water tank and booster reel on the rear.

The front system is possibly from Ansul, since there's an Ansul 20-pound extinguisher beside it.

The pump for all that water is probably on the body extension which is just visible at the rear. The guide rollers fore and aft of the booster reel are an unusual touch. The siren is mounted on the fender at an odd angle, suggesting either a dealer modification or maybe an addition by a photo retoucher.

This versatile piece of apparatus may have been bought through the dealership for an airport or industrial plant. The fact that the photo is in the archives suggests it was "factory approved," but it is neither the "Jeep Fire Engine" nor the "Jeep Crash Wagon," and I haven't seen it in any advertising.

Jeep Trucks

Howe FC-150 Howe Fire Apparatus of Anderson, Indiana built this unusual Forward Control FC-150 truck with both a multi-cylinder CO2 system and a water system; the logo on the door suggests it was destined for a small airport. I don't know if it was a one-off, but it is quite different from the many FC-170 pumpers built by Howe.
 

Howe FC-150 Ansul also offered configurations of their dry chemical system for the Forward Controls, but they don't seem to have been as popular as the CJ-3B version. Specs for their FC-170 list a 1000-pound tank, with two 100-foot hoses. This '59 FC-170 served the USAF at Thule in Greenland and is now on display at Goodfellow AFB in Texas. See Ansul Chemical for more details.

Swedish Air Force Probably the largest Jeep crash truck ever built was the Swedish Air Force's Räddningsbil 915 ("Rescue Truck 915".) It was based on the 1961 Willys FC-170H (heavy duty rear springs) and was fitted with an 800 kg (1,760 lb.) dry chemical tank and a 30 kg/second powder cannon. Again, I don't know how many of these trucks were built.

Pressure cylinders were mounted transversely at the rear; see also a left side drawing (170K JPEG). The truck was painted red. Thanks to Leif Hellström for the images.
 

Australia Also painted red was Willys Australia's "all-purpose fire/ambulance vehicle," which was not equipped in any way as a piece of fire apparatus, but was sold to the government for use at a number of airports. Willys Australia stated they would carry four stretcher cases, or eight fire crew as passengers, and that "In service they will be equipped with hoses and other firefighting gear and emergency first aid packs."

Amsterdam A 1952 Willys 473HT conversion by Kronenburg in the Netherlands, on the other hand, was thoroughly equipped as a fire truck. Delivered to Schiphol Airport in Amsterdam, it had a large Kronenburg pump on the front, a ladder rack, and plenty of gear stowage, but I don't know if the interior included a tank. It was reportedly in service until 1971.

Amsterdam In service it apparently pulled a trailer that may have been a dry chemical unit. Here its crew watches as one of Schiphol's big crash tenders (130K JPEG) lays down foam on a training fire.
 

Coventry, UK Aside from the Navy's experiments in the early 1950s, this J20 pickup may be the only Jeep to run a large foam gun. It clearly has a substantial tank in the back, but I don't have any details on the installation. The photo was taken at Coventry Airport in the UK circa 1997, and is courtesy of NTG842 on Flickr
 

Retford, UK Also in the UK is Retford Gamston Airport, a small facility in Nottinghamshire originally built as an RAF aerodrome during WWII. Their J20 Rescue 1 appears to have two tanks in the back, possibly dry chem and/or AFFF. Photo from 1997 courtesy of NTG842 on Flickr

Note: the U.S. Air Force also mounted some Ansul skid units in J20 trucks. And the U.S. Marine Corps had a similar dry chemical rig mounted on an M151 MUTT -- see Fire Jeeps in Vietnam.
 

USAF Class 530B The USAF generally preferred large fire trucks to Jeeps, but there is a Jeep connection to the Class 530B fire engine seen in this 1991 USAF photo. Several manufacturers including Kaiser Jeep and later AM General built the M44-chassis 6x6 trucks that were used in many roles by the US military for decades.
 

USAF Class 530B The 530 Class, a pumper for structural fires with a front-mounted pump, was produced starting in the 50s. The 530B had the PTO pump moved amidships, and the DRW version seen above dates from the 1960s. (9)

In the Vietnam era, the similar Class 530C had a foam deck gun added, making it suitable for airfield crash rescue duty, and it was used by the Army but apparently not the Air Force. Thanks to Jeff Ciccone and ArmyFireTrucks.com for this photo of his 530C.
