I used to run my Ultramarines fleet as follows:
Battlebarge - master of the fleet, 2 rerolls
Strike Cruiser
Strike Cruiser
Strike Cruiser
Strike Cruiser
6 Gladius Frigates
3 Sword Frigates
The cruisers were all squadroned together for superior firepower. Stuff did stuff, and was generally quite successful. Now, I actually have options! Given that I have no other ships (but am sorely tempted to do the following), here is my thought to a new-age list:
Seditio Opprimere - master of the fleet, 2 rerolls
Strike Cruiser - shield, prow bombardment cannon swap
Strike Cruiser - shield, prow bombardment cannon swap
Strike Cruiser - shield
Strike Cruiser - shield
6 Gladius Frigates
For starters, I'm excited the Seditio Opprimere made it into the fleet list, despite its equipment changes. Compared to a regular battlebarge, +25 points for extra shield and turret, minus a thunderhawk, and BC all around...seems very worth it to me. I worked out the maths on firepowers, and in most cases the VBB comes out a little stronger. The only downside I feel is the 100%/150% victory points rule. Has anyone used a VBB before, and has it been a game swinger?
Next, the SC. Extra shields are a definite go, and more thumping with BC is amazing. Again, they'll be squadroned together. It feels like they'll do their job like before, but much better.
Overall, I'm losing out on 5 squadrons of thunderhawks which is kind of a downer, but I still have 6 to fly CAP or do something mean when needed. The Sword squadron was always useful, but usually more just an afterthought. I'm not sure yet whether their loss will be hurtful or not, but that's what your opinions are for. I also have 40 points to spend, but I don't know what to do with it. I could just bring one Sword or Hunter...
