炸膛事件发生后,法国人把炮弹换装了更坚固的底盖,同时毒气腔也用水泥进行填充。

“让·巴尔”号战列舰在1940年5月法国沦陷时只有I号炮塔安装了炮管。原本用于II号炮塔的4根炮管中,在法国战败时有2门放在圣纳泽尔码头,其中有一门装载在货轮上准备运往北非,但货轮离港没多久即被德军飞机击沉;而另外一门据报则在德军占领港口前被拆解。第三门火炮在运往圣纳泽尔的途中被德军缴获,第四门则放在吕埃尔(Ruelle)的火炮工厂。

Richelieu had delay coils for the center guns of each turret fitted in 1947-1948 when a tighter dispersion pattern was desired in order to take the maximum advantage of radar fire control.  During tests at Mers el-Kébir in May 1948, the measured average dispersion at 26,500 meters (29,000 yards) was 525 meters (575 yards) without the firing delay and 300 meters (330 yards) with a 0.060 second firing delay (at this time the guns had all fired more than 200 shells without refit).
“黎塞留”号炮塔的中间两门炮在1947~1948年的改装中加设了延迟线圈,为的是减少弹着散布从而充分发挥火控雷达的性能。在1948年5月的测试中,“黎塞留”号如果不使用延时装置,在26500米(29000码)上的平均弹着散布为525米(575码);如果使用0.060秒的射击延时(在这个时间上所有炮管都可以达到超过200发的寿命),平均弹着散布则为300米(330码)。
 
 
 
 
These weapons were mounted in quad turrets, which were really more of a dual-twin arrangement.  The quad mounting was chosen as a result of weight considerations, as it meant less turret and protective belt armor was required, an important consideration for ships designed under Treaty limitations.  However, this configuration did mean that a single hit could destroy half of the main armament.  The individual guns were sleeved, although some descriptions imply that the relative motion of the guns in each pair was limited.  The French were apparently unhappy with the all-forward arrangement, as the design for the last ship in the class, Gascogne, returned to the more traditional fore-aft arrangement.
 
 
 
 
These guns were of complex assembly and a curious mix of modern and traditional French methods.  Model 1935 had 31 components consisting of an A tube, breech bush, twenty hoops, breech ring, four tubes to the muzzle ending in the muzzle bush and a locking ring.  Used a stepped loose liner that was held in place by a ring screwed into the breech end of A tube.  Model 1936 was simpler, having only 20 components with the number of hoops reduced to ten and the number of tubes reduced to three.  Both models were autofretted.
 
 




The Welin breech mechanism opened upwards automatically as the the gun ran out after firing.  It was hydro-pneumatically powered and balanced by counterweights.  An automatic lock with ten electric tubes for firing was fitted to the breech mechanism.
这种炮塔采用四联装设计,倒不如更像是“两个双联装”。采用四联设计主要是为了重量上的考虑,更少的炮塔意味着更短的主装甲带长度,(从而有更多的重量用于其他地方,)这是条约限制下舰船设计中一个很重要的权衡。然而,这种布局意味着一发炮弹就可能瘫痪战舰的一半火力。炮塔的四根炮管均可以独立俯仰,尽管有一些资料暗示某一侧的两根炮管之间的动作可能会有所限制。法国人明显对全主炮前置的布局颇有不满,这由本级的最后一艘舰——“加斯科涅”号又换回一前一后的主炮塔布局上可见一斑。


这些火炮工艺复杂,将法国传统和现代的技艺奇特地糅合在一起,其中M1935型就有多达35个部件。M1936型则是对前者的简化,只有20个部件。两种型号的火炮都是自紧的。


一共有21门火炮在1936至1940年被制造出来,另有9门则于战后完工。所有战后完工的火炮都被拆解,而战前完工的火炮待遇则好一些,一门“黎塞留”号的被放置在布勒斯特军港展出。

A total of 21 guns were built between 1936 and 1940 with an additional 9 guns built post-war.  All of the post war guns were scrapped, but the pre-war guns have fared better.  One gun from Richelieu is on display at the military harbor of Brest, near Recouvrance Bridge.  A second gun is on display at Gâvres, a third at Ecole Navale Lanvéoc Poulmic and a fourth is at Ruelle.  A fifth gun was removed from Richelieu as she was being scrapped and then used by the Italian Navy during the 1960s to test high-velocity projectiles.  This gun is now on display at the Naval Arsenal in La Spezia.
