At the time, jet propulsion was far from anything close to mature and most fighter designs were very short range. Turboprops offered a vast improvement in power over piston pounders and had good range, but jet tech advanced rapidly and quickly overtook it.

The Republic XF-84H Thunderscreech was the loudest aircraft ever built thanks to the tip speed of its propeller — supersonic. Here: http://en.wikipedia.org/wiki/XF-84H_Thunderscreech.
