Pakistan has received the first two of four Il-78 aerial refueling
aircraft from Ukraine. The Il-78 is a modified Russian Il-76 transport. The
tanker version can carry 105 tons of fuel. This will give Pakistan its first
aerial refueling capability.
the pioneer in aerial refueling, and largest practitioner, the U.S., is still
trying to select a new aerial tanker. The chief competitors are the U.S. made
KC-767, which has already been sold to Italy and Japan this year. The KC-767 is
based on the Boeing 767-200 airliner, which sells for about $120 million. The
767 has been in service since 1982, and over 800 have been manufactured so far.
Boeing developed the KC-767, at a cost of nearly a billion dollars, on its own.
Boeing also developed the original KC-135 tanker in the 1950s, and has since
built over 2,000 aerial tankers.
The current four
engine KC-135 carries 90 tons of fuel and can transfer up to 68 tons. Consider
that a B-52 carries over 140 tons of jet fuel, and an F-15, over five tons. A
two engine KC-767 carries about as much fuel as the KC-135. The European firm
Airbus, is offering the KC-30, based on the Airbus 330-300, which normally
sells for $160 million each. The KC-30 carries 20 percent more fuel than the
KC-767, and more cargo pallets (26 versus 19).
has long made itself useful carrying cargo and passengers, as well as fuel, and
both the KC-767 and KC-30 have more capacity for this. The KC-767 was developed
partly because it is about the same size as the KC-135 (wingspan is 156 feet,
ten more than the KC-135). Thus the 767 could use the same basing and repair
facilities as the 135. The KC-30 has been sold to Australia, and was briefly
selected as the new U.S. tanker (the KC-45A) until lawyers representing the
KC-767 intervened and forced a new round of evaluations.
