Thanks, Wolfman.
In the decades after the end of Space War I and during the reconstruction of Earth and the initial movement of colony missions, most ELINT, recon, C2, and AWACS support was provided by modified VF-1Ds (VEFR-1) or purpose-built ships derived from the VT-1 (VE-1). With the main fighter force transitioning to the VF-4 and VF-5000 variable fighters, a new platform with higher speed and more up to date technology was desired.
The solution Northrom-Grumman came up with was to fit an updated version of the VE-1's sensor and ECM suite in their successful and easily adaptable VA-3 Invader spaceframe. The new craft, called the VE-3 Howler, featured a second crewmember to handle the data load from the sensors and to control the powerful ECM and ECCM systems it was fitted with. The Howler remained completely combat-capable and retained all the pylons and carrying capacity of the base attack plane. Occasionally, in some squadrons and missions, the radar dome could be dismounted to improve speed and maneuver capablilities.
Eventually, the VE-3 was supported by new variable fighter-class craft with a similar mission, versions of the successful VF-11, the VF-17, and VF-171. Despite being slow and vunerable in comparison to the smaller ships, the VE-3 (Redesignated by NUNS as the RVA-3 and carrying an enhanced electronics suite) continues to serve in various planetary defense forces and outlying colonies.
