Coulson Aviation posted these photos May 25 of an assortment of Coulson-Unical helicopters at San Bernardino.
Paul Filmer sent us these photos of new S-70i Firehawk helicopters being tested at the Centennial, Colorado Airport.
Several wildland fire agencies have used the services of United Rotorcraft at Englewood, Colorado to retrofit Sikorsky S-70i helicopters — adding extended landing gear, external belly tanks, retractable snorkels, and rescue hoists. CAL FIRE is purchasing up to 12, Los Angeles County Fire Department is adding two more to their fleet, San Diego Fire-Rescue has received one, and Ventura County FD is converting three HH-60L Blackhawks formerly operated by the U.S. military. Coulson-Unical is taking a different approach, outfitting UH-60s with RADS internal tanks.
As we reported in March, Coulson Aviation is partnering with Unical Air, a new unit of the Unical Group of Companies, to create a heavy lift helicopter joint venture company that will build and operate Boeing CH-47 and Sikorsky UH-60 Blackhawk aircraft for aerial firefighting and other markets.
At the HAI Heli-Expo in Atlanta, March 5, 2019, Britt Coulson explained that they intended to install internal tanks in both models of helicopters. In the last few weeks the new partnership has been working to get their first aircraft of the joint venture carded, the company said in a Facebook post August 12, when they posted the photo below:
The camo paint job reminds me of Air Spray’s T-170. We’ll have to see if this makes it less visible to other aircraft when flying low and slow over a fire.
The livery on the Coulson-Unical helicopter is very different from their Blackhawk that was on display in Atlanta.
In the video below, Mr. Coulson describes the new Chinook and Blackhawk program they are undertaking with Unical. It was filmed at the HAI Heli-Expo in Atlanta, March 5, 2019.
The helicopters that are fully certificated and available in San Diego County for firefighting has grown in the last 15 or 20 years from practically nothing to eight now that an additional helicopter will be added to the mix.
Last week the County Board of Supervisors voted unanimously to split the cost of a Blackhawk helicopter with San Diego Gas and Electric. After the agreement is finalized, the helicopter will be positioned in the north part of the county during Red Flag Warning conditions.
Under the agreement SDG&E will cover the costs to operate the helicopter for the first two hours of any new flight, and the County will cover the second two flight hours. If used during a fire, the County could pay a maximum of $150,000 depending on flight time and reimbursements from the State of California or the federal government.
The County also shares a year-round lease with SDG&E for an Erickson Skycrane helicopter, which was put into action for several 2018 fires including the West Fire in Alpine, the Rangeland Fire in Ramona, the Pasqual Fire and the Recycle Fire in Campo.
The region currently has 10 aircraft available for initial attack:
- A U.S. Forest Service firefighting helicopter during fire season
- Three CAL FIRE fixed-wing aircraft, which consists of two retardant dropping airtankers and an air tactical supervisor plane,
- Three County Sheriff/CAL FIRE helicopters
- Two City of San Diego helicopters
- The SDG&E-leased Erickson Skycrane helicopter.
For an extended attack the County can also call on 26 military helicopters if available.
A U.S. Navy Blackhawk helicopter, an MH-60S, helped suppress a wildfire that was threatening homes on Guam. Not deterred by darkness, the flight crew dropped 4,200 gallons of water using an external bucket.
Here is how the squadron describes their mission:
“HSC-25 is the Navy’s only forward deployed MH-60S expeditionary squadron. We provide an armed helicopter capability for US Seventh Fleet as well as detachments to various commands covering a diverse mission set. Flying the MH-60S, HSC-25 supports permanently assigned detachments to the USS Bonhomme Richard homeported in Sasebo, Japan, and Commander, Task Force 73. These detachments perform logistics, search and rescue, and humanitarian assistance for US Seventh Fleet. HSC-25 is a tenant command on board Andersen Air Force Base, Guam. HSC-25 provides 24 hour search and rescue (SAR) and medical evacuation (MEDEVAC) service for Guam and the Northern Marianas Islands.”
Below are videos of them dropping on other fires.
The Vice President of Coulson Aviation describes the new Chinook and Blackhawk program they are undertaking with Unical. He also updates us on the firefighting aircraft they have working in Australia during the 2018-2019 bushfire season. It was filmed at the HAI Heli-Expo in Atlanta, March 5, 2019.

Firehawk helicopters are becoming more popular across the wildland fire services, especially in California.
A rather loose definition of a Firehawk is a Blackhawk, a Sikorsky UH-60 or S-70i, usually with an aftermarket 1,000-gallon external water tank for fighting fires, and a suction hose for refilling while hovering.
The earliest Firehawk that we are aware of was used in 1998 when Los Angeles County leased one with a belly tank from Sikorsky for about four months. (I’m sure someone will correct me if there’s an earlier occurrence.) Since then many of the newly acquired firefighting helicopters have been, or will be, Firehawks. CAL FIRE has signed contracts and expects to have 12 brand new converted S-70i ships within three years. Their first fully modified aircraft should arrive in June. Other examples of Firehawks include — Los Angeles County’s five (not all are fully modified yet), San Diego Fire Rescue has a one (but it is not yet fully modified), Ventura County has started converting three HH-60L Blackhawks into Firehawks, and Coulson is partnering with Unical to convert about 10 UH-60 Blackhawks. There are also other companies that have various configurations of Blackhawks with tanks.
As far as I know most of the above ships will have external water tanks, which require installing a longer landing gear to raise the ship, making room for the belly tank. Coulson, on the other hand, is installing a version of their removable RADS tank internally, and at least one company, Simplex, for example, has built another version of a removable internal tank. The company had it on display last year in Sacramento and at HAI Heli-Expo in Atlanta today.
For the record, Sikorsky, the company that manufactures Blackhawks, does not support the use of an internal water tank in the ships. They are not worried about the floor being able to hold it, but are concerned that in the event of a hard landing the tank, especially when full, could pose a danger to the crew. A belly tank, their theory contends, would not threaten the crew as a projectile, but could crush under the aircraft, absorbing some of the energy — not unlike the crumple zone in the front of a well designed automobile.
Ventura County has purchased three military HH-60L Blackhawk helicopters and is in the process of converting them into FIREHAWKS that will be used for fighting wildland fires, personnel transport, search and rescue, law enforcement, and medical evacuation.
Ventura County Battalion Chief Gary Monday said heavy maintenance and minor modifications were completed on the aircraft at HSI Sikorsky in Huntsville, Alabama, then two of the helicopters were painted at the United Rotorcraft facility in Decatur, Texas. One of them is now being ferried to United Rotorcraft in Englewood, Colorado to receive navigation and communication systems, cabin interiors, and a 1,000 gallon external fixed water tank with a retractable snorkel system. The landing gear will be replaced with higher gear to enable the installation of the belly tank.
The military had the aircraft originally configured by United Rotorcraft as dedicated MEDEVAC helicopters with medical equipment and patient litter systems, some of which will be repurposed in the new FIREHAWK configuration.
Ventura County, in Southern California, has a joint Fire Department and Sheriff’s Department Aviation Unit. In addition to the FIREHAWKS, they have one Bell 206 Jet Ranger, one 212 HP, one 205B, and two UH-1A Hueys.
“We are a full service 24/7 operation capable of Night Vision Goggle rescues and firefighting”, Chief Monday said, “with three 375 simplex tanks for nighttime water dropping missions, S & R missions, LE missions, and anything else.”
In 2016 one of the Hueys, Copter 7, developed a mechanical problem while fighting the Pine Fire on the Los Padres National Forest. It had to be stripped down in order to transport it via truck on a route that included a tunnel with a height restriction.
Thanks and a tip of the hat go out to Gary and Isaac. Typos or errors, report them HERE.
