I have noticed that Northwest Airlines has DC-10-30ER's, denoting extended range. However, I have never been able to find out what kind of range increase the DC-10-30ER's have over the regular DC-10-30. Could anyone shed some light on this unique aircraft model? It seems only 9 of these special models were ever produced according to

Straight out of Jane's All The World's Aircraft:
"Series -30ER. Developed version of Series 30, with range extended
still further by installing auxiliary fuel tank in rear of cargo
compartment. More powerful (240.2 kN; 54000 lb st) CF6-50C2B
engines. First order (for two) placed by Swissair in July 1980,
plus kits to convert two of its existing DC-10s to Srs 30ER
configuration. Other customers include Thai Airways International
and Toa Domestic Airlines of Japan."
That still leaves the question of by how much exactly the range was increased, which I unfortunately haven't been able to find out. Sorry.
