Erickson S-64 Aircrane Helitanker. It is the recognized worldwide as the best system for high
volume precision delivery of water, Class ‘A’ foam, and retardant from the air.
From tall-timbered wildland fires, to fast burning scrub brush fires, to crowded urban
interface fires, the Helitanker has a multiple-drop coverage level adjustment to fit each fire
scenario. Eight different coverage levels are available from an on-board microprocessor.
This microprocessor accounts for wind speed to open the tank doors and dump fire
retardant substances at a rate of 3.8 litres per 10 sq. metres (1 gallon per 100 sq. feet) to
30.4 litres per 10 sq. metres (8 gallons per 100 sq. feet).
The fixed tank fire suppression system includes a ram scoop hydrofoil that allows for 30
second refill in either sea water or fresh water sources. The flexible hose "Hover Snorkel"
fills in water sources as shallow as 45 centimetres (18 in.) in as fast as 45 seconds.
Straight stream horizontal delivery is accomplished by the optional "Water/Foam Cannon"
mounted on the front of the Helitanker. The cannon shoots a stream of water or foam mix at
a rate of 1,140 litres (300 gallons) per minute at distances of up to 48 metres (160 feet).
