Hello,
What changes to GTVA do you think are needed in order to be able to defend against Shivan menace in the post-FS2 period?
Here are my proposed changes:
First of all, GTVA needs to cut on destroyer losses. Since they introduced corvettes as a cheaper alternative, I belive that changes should go even further. Now those ships fulfill the following roles: Destroyers are command ships while providing anti-capital ship firepower and figher/bombers, while corvettes fulfill anti-fighter role as well as support firepower(judgeing by the fact that both Deimos and Sobek have slasher beams). IMO roles should be changed to destroyers being command ships, carriers and support ships, while corvettes should handle anti-figher and anti-capital ship roles. This would allow for lower loses among destroyers, because of two factors:
- they would only be required to participate directly in case of very big battles, where support-firepower would be needed
- even if they would be present on the battlefield, enemy would priortise destruction of corvettes giving them more chances to escape
Another advantage corvettes have over destroyers is speed and manouverability, that would be of great help in future confrontations with shivan forces, since GTVA does not stand a chance in a direct fight - guerilla tactics will be needed. This would of course require a development of new ships, and while we're at it, GTVA's R&D should definitely work on optimal hull shapes.
I'd base the new corvette over Deimos since it's a mighty fine one already. Here is a crude drawing of how I would do it

:

As you can see I used a new hull shape, that allows great AAAf and flak coverage. Here are the changes compared to Deimos:
-I exchanged one of it's Terran Slashing Beam for 2 AAAfs, because it seems to me like it's at worst an even trade when it comes to energy expenditure, and most probably should result in energy excess.
-I exchanged 3 Terran Slashing Beams for 3 Vasudan Light Beams, giving the corvette a respectable anti-capital ship firepower. Judging by damge values this exchange should result in excess energy.
-I exchanged piranha launchers for flaks, since they proved to be supperior.
I also hope that excess energy from those trades would be enough to allow this corvette to travel at 35 kps. This would get her on par with ICENI when it comes to speed, and allow outmanouvering of almost all enemy ships, which in turn is need in order to use those Vasudan Light Beams since they are all mounted on the front. AAAf and Flaks should make those corvettes plenty resilent to enemy figher and bomber attacks.
So, what changes to GTVA's doctrines, ships and the like do you think are necesarry?
