pressure on any given area of concern<br />

through their individual power to block<br />

presidential appointees from approval. If<br />

a Senator was concerned that some<br />

aspect of military operations was not<br />

being adequately addressed, he or she<br />

could use this power to bring attention<br />

to the problem and seek resolution.<br />

Following Boeing's successful<br />

protest against the Northrop Grumman-<br />

EADS tanker contract, the Alabama<br />

Senate delegation put a hold on all<br />

presidential nominees for DOD<br />

positions. This reportedly was due to<br />

their unhappiness that the tanker<br />

contract was overturned, as the aircraft<br />

would have been built in Alabama. This<br />

same blocking procedure could be used<br />

in an attempt to remedy an issue of<br />

safety or maintenance practices.<br />

CONCLUSION<br />

It's impossible to declare any operation<br />

or procedure as completely safe, no<br />

matter how carefully audited and<br />

conducted. Accidents can happen,<br />

despite the best preventive efforts. But<br />

the U.S. military's acceptance of<br />

standardized, safety-based refueling<br />

procedures, along with the legislative<br />

branch's numerous institutional<br />

oversight groups, have been effective in<br />

proactively addressing safety concerns.<br />

Together, the checks and balances<br />

provided by these institutions, along<br />

with the dedicated work of personnel in<br />

the field, appear to make it unlikely that<br />

the lapses blamed for the loss of the<br />

RAF's Nimrod could fester within the<br />

U.S. armed forces with similarly tragic<br />

results.<br />

AIRCRAFT REFUELING<br />

SPECIAL EQUIPMENT<br />

U.S. Air Force Aerial Refueling<br />

Platforms:<br />

The KC-135 Stratotanker provides<br />

the core aerial refueling capability<br />

for the U.S. Air Force. The KC-135<br />

is derived from Boeing's model<br />

367-80 aircraft, from which the 707<br />

airliner also was developed. The<br />

first KC-135 was delivered to the<br />

U.S. Air Force in 1954, the last in<br />

1965.<br />

Most KC-135s have been<br />

retrofitted with CFM International's<br />

CFM-56 engines and are<br />

designated as R or T models. Thus<br />

equipped, these aircraft can carry<br />

150,000 pounds of transfer fuel.<br />

The Air Mobility Command<br />

manages an inventory of more<br />

than 415 Stratotankers, of which<br />

the U.S. Air Force Reserve and U.S.<br />

Air National Guard fly 235 in<br />

support of the AMC's mission.<br />

The KC-10 Extender<br />

The KC-10 Extender is a derivative<br />

of Boeing's DC-10-30 airliner. It<br />

entered service in 1981.<br />

Capable of carrying 356,000<br />

pounds of transfer fuel, the KC-10<br />

can refuel via boom at a maximum<br />

rate of 1,100 gallons per minute,<br />

and via a probe and drogue<br />

system at a maximum refueling<br />

rate of 470 gallons per minute. The<br />

Air Mobility Command currently<br />

has fifty-nine of these aerial<br />

tankers in its inventory.<br />
