and as an add-on two drawings from Squadron Signal N° 89, which mentions
the Volpar AT-28F, too. The piston engine was replaced with two Garrett TPE 331-3U turboprops
of 904 hp each, using so-called "Package Power Conversions" off-the-shelf propulsion units.
The nose section, repacing the piston engine was detachable and easy and quick exchangeable.
Noses with four .50 caliber guns, ECM equipment or for photo recce were designed.
Additionally the AT-28F had six underwing hardpoints for up to 4,000 lbs.
Claimed performance were a top speed was 330 mph, service ceiling of 28,000 ft and a range
of 1,540 miles (2,800 with aux tanks of 165 gallons each).
