No, no. The A 37 was a modification of the earlier T 37, which was
grotesquely underpowered, with those French turbines that put out about 1200
lbs. each, less thrust than noise. The A 37 was designed as a more
affordable ground attack aircraft for what was called at the time
Counterinsurgency. It could deliver a lot of stuff for a smaller price tag
than the high priced spreads of the day. The A model required a lot or
redesign, as the engines went through a large cast/forged center section of
the spar. The replacement engines were about 6000 lbs.each, standard pure
jets of the day.
Of course the Lightning was in a different class, designed for a very
different role, but the pounds vs. weight counts in any thing with wings.
Now, Hawker-Beechcraft is doing the same thing with their T-6, reengined it
with a larger PT6 and hard points, and is in competition with the Brazilian
equivalent for a large USAF contract. It's advantage (along with the
Brazilian) is low cost of acquisition and maintenance.

You had better change Wikipedia then, Bill. It has the empty weight as over
6,000lb, but with each engine pushing out less than 3,000lbf.
I'm sure that the A-37 was pretty pokey, but the Lightning was in a
different class: thrust, weight, speed etc . . .
. . . and difficulty to fly, I should say :-)
