Airports are not only runways and terminals, but also complex security infrastructure where fire engines play a critical role. Unlike its urban counterparts, airport fire trucks (ARFF — Aircraft Rescue and Firefighting) are designed for lightning-fast response to aircraft emergencies, where every second determines the survival of passengers and crew. Their task is not just to extinguish the fire, but to prevent catastrophic consequences: explosions of fuel tanks, collapse of the fuselage or the spread of flames to neighboring objects.
In Russia, the requirements for such machines are regulated Federal Aviation Regulations (FAP-128) and international standards ICAO (Doc 9137). For example, the time of arrival of fire crews to the scene of an emergency should not exceed 3 minutes for airports of category 9 (the highest), and the supply of fire extinguishing agents must be sufficient to extinguish a fire with an area of up to 2800 m². But how do these machines work, what technologies allow them to work in extreme conditions, and why their cost can exceed 10 million rubles? Let's look into it in detail.
Modern ARFF-cars are not just trucks with a tank and a pump. They are equipped with turbocharged engines with power up to 1500 hp, a high expansion foam system, robotic monitors and even thermal imaging cameras to search for fires in thick smoke. Their bodies are made of fire-resistant composites, and the chassis is adapted for driving on the unpaved sides of the runway at speeds up to 130 km/h. Moreover, the weight of such a machine can reach 50 tons - comparable to a medium tank.
1. Categories of airports and corresponding requirements for fire engines
The classification of airports by fire safety is determined aircraft lengthwhich they are able to accept. For example, an airport category 7 designed for aircraft type Boeing 737 or Airbus A320, and the category 10 - on Airbus A380 or Boeing 747-8. Depends on the category:
- 🔥 Minimum number of fire engines (from 1 to 5 units in constant readiness).
- ⏱️ Arrival time to the place of emergency (from 2 to 3 minutes).
- 💦 Volume of fire extinguishing agents (from 3000 to 18,000 liters).
- 🛠️ Availability of specialized equipment (for example, lifts for extinguishing the upper parts of the fuselage).
In Russia, the majority of airports belong to the categories 7–9, which determines the use of machines like Rosenbauer Panther or Oshkosh Striker. For example, in Sheremetyevo and Domodedovo are exploited Panther 8×8 with foam reserve 12,000 liters and water 14,000 liters, which allows you to extinguish a fire in an area of up to 4000 m² without refueling.
2. Design and technical characteristics of ARFF machines
Airfield fire trucks are radically different from their urban counterparts. Their key features:
Chassis and engine:
- 🚛 Most cars are built on the basis multi-axle chassis (6x6 or 8x8) for increased stability when traveling at high speeds with a full load.
- ⚡ Engines - diesel Caterpillar, Detroit Diesel or Scania power 1000–1500 hp, equipped with a pressurization system for operation in high altitude conditions.
- 💨 Turbochargers allow you to accelerate to 130 km/h for 25–30 seconds (for comparison: a city fire truck accelerates to 100 km/h in 40+ seconds).
Extinguishing systems:
- 🌊 Fire monitors with a water supply range of up to 100 meters and foam - up to 80 meters. Controlled remotely from the cab.
- 🧪 Foaming agents high expansion ratio (up to 1:20), allowing you to create a dense layer of foam to insulate burning fuel.
- 🔥 Inert gas systems (for example, Halotron) for extinguishing fires in aircraft electrical equipment.
Critical fact: modern ARFF machines are equipped with a CAFS (Compressed Air Foam System), which mixes water, foaming agent and compressed air, creating “wet foam” with increased stickiness. This allows you to extinguish vertical surfaces (for example, the tail of an airplane) without the fire extinguishing agent running off.
| Characteristics | Rosenbauer Panther 6×6 | Oshkosh Striker 8×8 | ZIL-433462 (Russian equivalent) |
|---|---|---|---|
| Engine power, hp | 1200 | 1500 | 450 |
| Water volume, l | 9000 | 14 000 | 4000 |
| Foam volume, l | 1200 | 1800 | 500 |
| Water supply range, m | 90 | 100 | 60 |
| Cost, million rubles. | ~80 | ~120 | ~15 |
ARFF machines must be certified according to the standard NFPA 414 (USA) or EN 1846 (EU), which guarantees their compliance with international safety requirements.
3. Tactics for using fire trucks at airports
The algorithm of actions of fire crews at the airport is strictly regulated. When receiving a signal about an emergency (for example, from a dispatcher or system ADS-B) the machine must:
- Leave the fire station within 20 seconds.
- Move along a pre-agreed route, avoiding intersections with runways.
- Arrive at the scene of the emergency no later than 3 minutes (for category 9 airports).
- Immediately begin extinguishing, taking into account the type of fire (fuel, electrical equipment, cargo).
Features of extinguishing aircraft fires:
- 🛩️ Priority is saving passengers. Firefighters first provide evacuation and then begin extinguishing the fire.
- ⛽ Fuel fires extinguish with high expansion foam, since water only spreads the burning fuel.
- ⚡ Electrical fires (for example, in batteries Boeing 787) require use Halotron or powder fire extinguishers.
⚠️ Attention: When extinguishing aircraft with composite materials (for example, Airbus A350 or Boeing 787) Do not use water under high pressure - this can lead to delamination of the structure and collapse of the fuselage. Instead, low intensity foam is used.
Used at airports three main extinguishing tactics:
- "Attack from the flanks" — cars approach the plane from both sides, blocking the spread of fire.
- "Stewing from above" — using lifts or monitors, foam is supplied to the fuselage roof.
- "Isolation of the source" - if there is a fire in the engine, it is cut off with foam, preventing the fire of the fuel tanks.

4. Russian and foreign models: comparison and features
Austrian companies lead the world market Rosenbauer and American Oshkosh, but Russia also produces specialized machines adapted to local conditions. Let's look at the key models:
Foreign manufacturers:
- 🇦🇹 Rosenbauer Panther - the most common model in Europe. Equipped with a system FireDex for automatic foam mixing.
- 🇺🇸 Oshkosh Striker - used in the USA and UAE. It features reinforced cabin armor to protect the crew during explosions.
- 🇩🇪 Ziegler Z8 — a German car with a hybrid power plant (diesel + electric motor to save fuel).
Russian analogues:
- 🇷🇺 ZIL-433462 "Typhoon" — a budget option for small airports. Equipped with a pump NTsPN-40/100.
- 🇷🇺 Ural-532366-1010 - car on base UralNext with foam reserve 1500 liters. Used in Siberia and the Far East.
- 🇷🇺 KAMAZ-63968 "Typhoon-K" - the latest development with a cabin protected from blast waves.
The main difference between foreign models is process automation (for example, Rosenbauer equips machines with a system AutoPilot for semi-autonomous control of trunks). Russian machines are cheaper, but require more operator participation.
Why don't they use electric ARFF machines in Russia?
Electric fire engines (eg Rosenbauer RT on batteries) are not yet used at Russian airports due to climatic restrictions: at −30°C, the battery capacity drops by 40–50%, which is critical for operation in the Far North. In addition, the infrastructure for fast charging of such cars is not available at most airports.
5. Maintenance and checks: how to keep machines ready
ARFF machines pass daily, weekly and monthly checks, and also full maintenance every 6 months. Basic procedures:
- 🔧 Daily inspection: checking the oil level, tire pressure, and the functionality of the warning lights.
- 💧 Weekly check: pump test, tank tightness control, calibration of foaming systems.
- 🔥 Monthly exercises: imitation of fire extinguishing with full testing of tactics.
Particular attention is paid to:
⚠️ Attention: In winter, vehicles must be equipped anti-icing additives for water, since frozen liquid in the hoses can lead to their rupture when supplied under pressure. It is also necessary to check the operation of the cabin heaters - at −40°C, an unheated engine may not start.
The service life of an ARFF machine is 15–20 years, but every 5 years a deep modernization is being carried out with the replacement of electronics and hydraulic systems. For example, in Pulkovo cars Rosenbauer 2010 models were modernized in 2020, receiving new systems CAFS and thermal imagers FLIR.
6. Development prospects: what awaits airport fire trucks
Trends in the development of ARFF machines are associated with automation, environmental friendliness and increased extinguishing efficiency:
- 🤖 Autonomous systems: companies Rosenbauer and Oshkosh testing machines with function Follow Me, where the fire truck automatically follows the lead vehicle along a GPS route.
- 🌱 Eco-friendly fire extinguishing agents: Instead of traditional fluorine-containing foams, they switch to biodegradable compounds (for example, 3M Novec 1230).
- 📡 Integration with airport systems: machines will receive emergency data directly from ADS-B and MLAT, which will reduce reaction time.
It is planned to launch production in Russia hybrid ARFF vehicles based on KAMAZ with electric pumps and energy recovery during braking. This will reduce fuel consumption by 20–30% without loss of power.
When choosing a fire truck for an airport, pay attention to certification according to ICAO Doc 9137 and availability of a system CAFS — this guarantees compliance with international standards and increases the chances of successfully extinguishing complex fires.
7. Frequently asked questions about airport fire trucks
❓ Why are fire trucks at airports so big?
The dimensions are due to the need to transport huge volumes of water and foam (up to 18,000 liters), as well as provide high cross-country ability on soil and snow. In addition, a large machine is more stable when supplying water over long distances (up to 100 meters).
❓ How much does one such car cost?
The cost depends on the model and configuration:
- Budget Russian cars (ZIL, Ural) — 10–20 million rubles.
- Foreign models (Rosenbauer, Oshkosh) — 50–150 million rubles.
- Vehicles with hybrid engines and automated systems - up to RUB 200 million.
❓ Can city fire trucks be used at airports?
No, city cars do not meet the requirements ICAO by:
- The volume of fire extinguishing agents (there is enough in the city 2000–3000 liters, at the airport you need 9000+).
- Arrival speeds (city cars arrive in 5–10 minutes, and at the airport the norm is 2–3 minutes).
- Specialized equipment (monitors, thermal imagers, systems CAFS).
❓ How often are exercises conducted using ARFF vehicles?
According to FAP-128, exercises are conducted:
- Monthly – practice of departure and maneuvering.
- Quarterly - full extinguishing of a simulated fire with the participation of rescuers.
- Every year there are complex exercises with simulated evacuation of passengers.
❓ What fire extinguishing substances are prohibited at airports?
Vtsia is prohibited from using:
- Powder fire extinguishers for extinguishing fuel fires (they do not cool the surface).
- Carbon dioxide (CO₂) to extinguish fires in the aircraft cabin (risk of suffocation for passengers).
- Water without foaming agent for extinguishing jet fuel (causes fire to spread).
