In 3021, a number of Neptune class submarines defeated a lance of Dragon class mechs on New Ivaarsen. The battle prevented the disabling of the C3 network on that world which helped the Davions win the day.
In 3039 after the Forth Succession War, Hanse tried a similar war with his arch enemy the Draconis Combine, and thus waged this conflict. However, the Kuritans were ready, and learning that part of their counter offensive was going to involve a fight on Galtor - home of the Neptune - some wanted payback against those very vessels.
In this, a group of Neptunes are pounced upon by a large company of mechs, most of which are Dragons, eager for revenge. Insitgating tactics to defeat these subs, the mech corale the sub and start to pick them off with concentrated laser and some torpedo loads in their LRM/SRM units, this includes a Madra is equiped with nothing but SRTs to guarantee the Neptune's destruction.
I always wanted to do an underwater scene and I loved the backstory of the Neptune, why it was build and its function, hence again why its one of my favourite vehicles. However, I think mechs would be far deadlier in deep water (not an ocean) than a sub due to turning circles.
I liked how the undersea blasts came out, and the lasers - not over the top or strange.
The best part are the mechs - I was going to add detail but I felt that would detract some from others, so I made them sillouettes with just the glare of their cockpits to show that is what they are - oh and give a demonic look as they take on the Neptunes.
Like to hear your thoughts please.
