Marcus turns assassin as he tried to eliminate a Japanese Admiral.

I needed to dig out a space mat in connection with another project this week and as a result just fancied a game of Full Thrust. I’d sketched out some ship diagrams previously and done a couple of other designs. The scenario I threw together was loosely inspired by Operation Vengeance, the plan to kill Admiral Yamamoto which took place on April 18, 1943, during the Solomon Islands campaign in the Pacific. Yamamoto, the commander of the IJN Combined Fleet was deliberately targeted by USAF aircraft following US Navy codebreakers identifying his flight-plan in the area of Bougainville Island.

In this scenario, Admiral Maya of the IJN is present aboard the Heavy Cruiser Chokai escorted by the Light Cruiser Mogami and a frigate, the Fubuki, having visited an installation in the Bougainville asteroid belt. Royal Navy forces, having been made aware of his presence in the area have penetrated deep into IJN space using light forces with the intent of springing an ambush using the belt as cover. The Chokai needed to exit the far end of the table for a win.

The British forces are composed of the (very) light carrier Pandai (with just one fighter group), two destroyers, the Triton and Ganymede, and four pulse torpedo armed corvettes: Leda, Ersa, Elara and Dia. I set up the game initially and played a couple of turns but then match abandoned for dinner! More of that anon (the abandoned game, not dinner!) I set up again the next day for take two.

Turn 1
The IJN ships entered from the short navigating carefully at speed 3 but accelerate to 4 on detecting trouble. Both the Mogami and Fubuki detect the Leda and gain a hit each on the approaching corvette. The Callisto responds from beyond Leda to gain a hit on the Mogami.

Turn 2

The IJN fleet accelerate to 6 with Fubuki forced to make a slight turn to port to avoid an asteroid. The Ganymede to the port of the IJN fleet became exposed from behind an asteroid and suffered combined fire from the Japanese. Chokai put four hits on the Ganymede to her port from the A and 3 B turrets. Mogami gets an unlikely three hits from her 3 B’s to turn Ganymede into a flaming wreck. However, before she succumbs Ganymede fires on Chokai, but the one shot on target is deflected by Chokai’s shield. To starboard the Fubuki opens up on the leading RN corvette, the Leda, again achieving two hits. However, both Leda and Ersa reply. Leda gets just one hit with her pulse torpedo, but this produces a damage roll of 5. Boom! Both sides have lost one ship

Turn 3

Accelerating now to a velocity of eight, the remaining Japanese ships also make a one point turn to Starboard to manoeuvre through the asteroid field and escape. Chokai open s up with her A battery at close range on the Dia but all 3 dice miss! By contrast the 2 B turrets fired at Ersa produce 6645! 4 hits from four dice! Ersa nevertheless manages to put a pulse torpedo into Mogami at close range on a 4 and rolls 4 damage before succumbing to the fatal damage from Chokai. Leda does exactly the same; a roll of 4 and a damage roll of 4 also against the Chokai. Dia misses her shot while finally Elara rolls a 5 for a hit. Elara rolls a damage of 6! The heavy cruiser now only has two damage boxes left, but the critical damage “threshold” checks result in the A turret being placed out of action. Most unfortunately though the FTL drive has been put out of action. Callisto tries to finish off Chokai at close range but her 2 B’s and a C turret get two hits of 4, but are blocked by the Chokai’s shields.

The RN Pandia, which has been lurking out of sight behind an asteroid launches her fighter group.

Turn 4

Despite the heavy damage taken by Chokai, her systems are largely intact. However she needs to get the FTL up and running if she is to escape. The damage control party attempt this but needing a 6, only roll a 5. She nevertheless pours on further acceleration in a bid to escape the onslaught, moving to velocity 10. Mogami has to slow slightly (-1 velocity to 7) to manoeuvre.
While Pandia’s fighter close in on a Chokia which is now opening up the range from Callisto, Chokia brings Pandia under fire with her 3 remaining B turrets at short range. An unlikely 66555 results in 7 hits! With just two damage boxes remaining Pandia also loses a point defence system. Mogami finished her off with a 6 and 4 from her 3 B’s resulting in 3 damage. However, while the fighters closed in on Chokai, Callisto again fired with her 2 B’s and C (5 dice) to get to 6’s and 4 damage. Chokai is eviscerated and the Admiral lost.

Despite the conclusion of the scenario objective, I played on the next couple of turns to see if the Mogami could at least make an improbable escape.

Turn 5

The Mogami runs, accelerating by +3 to a velocity of 10, chased by Pandia’s orphaned fighters. Mogami uses her area anti fighter weapon to shoot at the fighters and bring two down on a 6, but not before they launch their weapons; 125566 results in 6 hits including a point defence system and a firecon. In Mogami’s rear arc, Callisto continues to blast away with 5 dice and does a further two damage.

Turn 6

So close to the edge of the asteroid field now, Mogami accelerates to 13. Although the fighters trail they are still in range. However, although the range has opened to the extent that it reduces Callisto’s firepower to just 2 dice, a roll of 5 and 6 did three damage, finishing off the gallant Mogami. In fact although the pictures show that Mogami was pursued by the fighters I subsequently realised that they are armed with single shot weapons. But for quite a lucky roll from the Callisto, Mogami might have escaped to at least advise the IJN High Command of the disaster.

That was not the least of my mistakes! Evaluating the game I noticed something about the corvettes and crunched the numbers on the design again. I don’t think I had ever finished the calculations on this whenever I had first made them, because I had them costed out at 42 points. I now made them 76! This meant that the RN which I had earlier calculated as being down c. 30 points was actually up around 100! I also noticed page 31 of the FT rules (ship design) which noted that fighter groups should only be carried by carriers and dreadnoughts. I hadn’t really considered what this meant before, but I wondered subsequently if that outlawed “jeep” carriers like the Pandia. I am not convinced though. Even if that was the intention, such small carriers existed in World War Two and continued with carriers such as the Invincible class in the RN and a number of others armed with V/STOLs. Balancing a scenario on points is not critical, especially in such a solo, narrative game. I tried to play a “fair” game, but it is clear in retrospect that the asteroid field gave a substantial advantage to the RN flotilla.

I mentioned the earlier, abandoned game. I only played at most three turns and perhaps the third wasn’t completed either, I can’t quite recall. What was interesting is that the corvettes acquitted themselves terribly in that game, while the fighters made very early work of the Chokai. I think that this points out the power of fighters in this scenario where there was no fighter cover for the IJN. That could be balanced out in the scenario by an escort squadron from Bougainville. In any event, I would like to give the scenario another try with a better balance just out of interest.

In discussion afterwards with members of the club, they asked how I ran the ”opposition”. As I described above I played it as a more narrative game, but this did make me think about describing a couple of options for manoeuvres (almost “matrix game” like) to myself and then rolling to select which applied. The firing/target selection is less of an issue I think.
