Defend the Homeworld!

Next up in the (irregular) series of vehicles for Traveller, a custom design from Striker, for ground defense against space-based threats (invaders, pirates and such):
After some discussion on G+, I realized I could have built this craft much more efficiently. So, the first one is the improved version, the original behemoth is second.

The Sentry-class mobile anti-spacecraft platform works in conjunction with Skysweeper-class radar vehicles to detect incoming hostile spacecraft. Once the target is identified, both vehicles go in motion to frustrate counter-battery attacks on the vehicles. (note the high speed) Multiple Sentries can connect to one radar vehicle and so coordinate their firepower.
The Sentry-class is technically larger than a standard space fighter, but significantly less expensive.
