In response to the obvious question - what does this have to do with the Middle East? While doing some research on the U.S. strike on the Iranian nuclear facility at Fordow nuclear enrichment facility, specifically the use of aerial refueling to support the B-2 bomber attack, I discovered an interesting fact about what I believe is a Royal Air Force refueling shortfall.
Over the last few years, the
Royal Air Force (RAF) has acquired more modern aircraft that normally would
allow significant power projection capability in addition to enhanced regional
operations.
These include:
- E-7A
Wedgetail airborne early warning and control aircraft
- P-8A
Poseidon (RAF designation Poseidon MRA1) maritime patrol and - anti-submarine
warfare aircraft
- C-17A Globemaster III strategic airlifter
- RC-135W Rivet Joint (RAF name Airseeker) signals
intelligence (SIGINT) platform
All of these aircraft were built
by Boeing Defense, Space & Security, and include aerial refueling
capability via the flying boom system. In this system, fuel is transferred from
a tanker aircraft to a receiver aircraft via a rigid, telescoping tube called a
boom, which is controlled by a boom operator on the tanker.
This system is used
extensively by the U.S. Air Force, as well as air forces that operate many
American built aircraft, such as the F-15 Eagle, F-16 Fighting Falcon, and the
F-35A.

Wedgetail Although the RAF operates a fleet
of 14 aerial refueling tankers, none of them are equipped with the flying boom
system.
The RAF tankers are Airbus A330
Multi Role Tanker Transport (MRTT) aircraft and are only equipped with a
probe-and-drogue refueling system. In this method, a flexible hose with a
drogue (a small parachute-like basket) is trailed from the tanker aircraft, and
the receiving aircraft inserts a rigid probe into the drogue to receive fuel.
This system is used by the U.S. Navy* and Marine Corps, as well as air forces
that operate some U.S. built aircraft such as the F-18 and some versions of the
F-35. Most foreign-built aircraft, many in service with the RAF, are designed to
use this system as well.
Royal Air Force Voyager KC3 refueling two Eurofighter TyphoonsAirbus offers a flying boom
capability for the A330 MRTT, however, there are no plans to retrofit any of
the existing 14 RAF KC2 or KC3 tankers with the Airbus Aerial Refueling Boom
System (ARBS).
Of note, the 14 Airbus A330 MRTT
Voyager aircraft are owned, managed, and maintained by a private consortium
called AirTanker Services Ltd on a 27-year contract that was signed in 2007.
The RAF leases these aircraft and its crews operate them for military
operations.
This lack of flying boom
refueling capability presents an issue for RAF operations planners. Should the
United Kingdom have a need to deploy an expeditionary force to anywhere beyond
the unrefueled range of these aircraft, they will need to obtain assistance
from one of the air forces that operate boom equipped tankers. Also, they have
to consider how long they will want the E-7 and RC-135 to remain on station
providing command and control, and electronic intelligence support.
Who will they rely on? Obviously,
their first call will be to the U.S. Air Force. There is an already established
relationship between the two air forces. If for some unlikely reason the U.S
cannot or will not support the RAF, there are other options. These are the air
forces that operate boom-equipped tankers: United States, France, Spain, Italy,
Turkey, Australia, Saudi Arabia, United Arab Emirates, Qatar, Israel,
Singapore, South Korea, Japan, and Chile.
NATO also operates nine
boom-equipped aircraft in a partnership of the Netherlands, Germany, Norway,
Belgium, Luxembourg, and Czech Republic.

P-8 maritime patrol aircraft and E-6B communications relay aircraft require
flying boom refueling, and thus are normally refueled by U.S. Air Force
tankers.
