IL-76: World's Fastest, Longest-range,
Highest-Volume, Air-Tanker
The IL-76 turbofan jet
cargo aircraft is by far the world's most formidable, fastest,
longest-range, air tanker. For fire fighting and ocean oil spill
dispersal, as well as for dispersion on (e.g.) chemicals plants in
upset conditions, it comes outfitted with a twin-tank system capable
of carrying either 100,000 or 135,000 pounds of liquid and can be
filled and ready for takeoff in 15 minutes. In its smaller 100,000
pound version, this patented system is capable of depositing more
than 3,608-3,937 ft x 263-295 ft of liquid in one 8-10 second pass -
water only - and one 15-20 second pass with foam additive. This is
up to five (5) times greater than the volume deliverable by the
largest-volume "water bomber" commonly used in the world today.

An IL-76 can also offload its twin tanks in a single salvo, yielding
a smaller, heavier, saturation drop pattern for use on particularly
hot or powerful blazes or other special situations.
The aircraft is equipped with heat-seeking devices and associated
computer-driven fire data simulations providing assistance with
aiming the drop for maximum effect on mass fire.
In fire fighting, liquid drops are normally delivered at a speed of
151 knots at 300 feet altitude. Liquids descend vertically, as rain,
evenly penetrating forest canopy, thereby optimizing the
fire-retarding effect on the forest floor.
Liquids mixes certified for use with the aircraft by Ilyushin Design
Bureau, include Monsanto PHOS-CHEK WD 881. Prospects for
certification for slurry use are excellent.
A fully-integrated emergency service complete with spares and
certified EMERCOM crew for fire fighting, humanitarian relief, and
disaster mitigation and prevention stands ready for emergency
deployment. Emergency availability is managed on a 48-hour, best
efforts call-out basis. Plans for radialogical disaster prevention
are also offered.
