My first submarine attempt. The HMUb Hwalen, a "cruiser submarine" launched in 1978. It carries 12x Rb08U antiship missiles. Which is the extened range, sublaunched version of the Rb08 ASM. Its primary purpose is to attack enemy battlegroups and harbours and cosatl airfields.
In 1991-96 all boats where altered to TLAM Tomahawk because the land attack seeker of the RB08U was naver satisfiying.

HMUb Hwalen ("the Whale")
98x12x12m
4000t
Diesel electric propulsion, 18kts max...
12x1 RB08U ASM
8x 533mm torpedo tubes for wireguided torpedoes

I'm not good at all with subs, but I think your art style makes it a great favour! The idea of a RB-08 armed sub is also very pleasing.

But what kind of land attack seeker would it have if designed during the 70:s? Tomahawk became operative in the early eigties.. when was GPS up and runnig - a small enough to fit in a missle seek? I imagine the RB08U has a high resolution radarseeker or IR homing combined with internal navigation.

I have to say I can't see how you're going to launch an Rb08 from a submarine.

wasn't the Rb08 an rail launched missile? with attachable wings?
- thinks of the V1 and regulus launching subs -
well like that, not like this

IRL Rb-08 was a rail launched missile. But my AU use in both boxlauncher and now on submarines.

I think it is possible. Many russian as well as american subs launched submarine launched cruise missiles in the 50:s already.

The missile is stored in a slightly angled silo (similar to the Oscar's). The missile itself is fired to the surfaced by compressed air and in the final phase its rocket boosters. The protective plastic shield falls of when it brakes the surface so the wings can flip and and the rocket thrusters push it to alitiude where the turbojet engine kicks in. Missiles are fired from periscope depth.

Abit like the UGM-84 Subharpoonprocedure

with the difference that the harpoon has completely different wings, which is what troubles me in this setup.
I would think the launch installation for an missile like that to be like this

Indeed they did, bu they had to surface before firing.
The SubHarpoon comparison doesn,t really work either. The Rb08 is a miniature aircraft which makes it very hard ro design a float-free cocoon that can withstand the pressure and still unfold in a way that makes takeoff possible. Just keeping the cannister from broaching is going to be a major hurdle and underwater launch isn't an option because of the wings.

Thiel is right.A different missile is needed.What about a subRb15?

This is the solution for the first class of missile carrying submarine.
To early RB15U isn't operative until 1988 (with the next class of subs.)

The launch of RB08U. Same warhead, turbo jet engine, seeker. slightly adjusted body to fit in the launch canister. Four booster instead of the normal 2 are fitted (like a sea slug)

The body is altered and looks more similare to the US AGM-86 ALCM


1. Silo is opened
2. Silo flooded
3. Missile canister is fired with compressed air (similar to a polaris launch)
4, Rocket boosters egniht, canister is blown apart by explosive bolts
5. wings swing out (main wings are folded backwards like a F-111, tail is shortened an folded down so they pop up)
6. When the missile reaches altitude the turbo jet starts up and the rocket boosters fall off.

I have more problem with a descent land attack seeker with 1970s technology
