In some ways the Gloster Javelin was a less-than-ideal engine test platform, but two examples performed exactly that role
ENGINE TEST JAVELINS
With its twin engines situated in wing-mounted nacelles, the Gloster Meteor proved ideal for testing alternative power units, such was the relative ease with which the nacelles could be adapted.The manufacturer’s follow-on Javelin all-weather fighter had its twin powerplants housed within the fuselage and so, in theory, was less suited to operations as a testbed, at least outside the area of fitting new versions of its standard Sapphire engines. But two Javelin FAW1s were adapted to take entirely different units.
