Ok maybe from other angle ... if this bow mount is such wonderful and marvelous place for weapon, why nobody put it there. There must be a good reason. I'm not educated shipbulider, not even a sailor but as I only travel couple of times on board ferry in bad weather over Baltic. And thats hard a comparison to North Sea or North Atlantic. For me it is the worst possible position for any weapon, stability, salt water, waves ... unable of use of this weapon in not that bad weather. Even my logic say this is a very, very bad idea. Especially when you want to use a very complex and fragile weapon system like laser.
1.) There is no reason to assume fragility. The Phalanx is probably the most finicky POS on a USN platform and I have shown it being placed directly on the bow (granted higher) and it is routinely placed on protruding platforms on carriers that are directly exposed to the elements. Salt is universal, you can't get away from it no matter what. Salt spray is actually worse than straight up waves as waves wash off deposited salt while spray just deposits more on top.
2.) The bow on most smaller vessels is taken up by other things, generally anchors. I have moved this to the deck below
3.) Most main weapons systems have bulky magazines that need to be in direct contact with the launcher (sometimes the the magazine is the launcher, see VLS). This means there simply isn't any room in the bow to accomodate all this. This weapon has no magazine, it just has to have power run to it. That being said bow guns are pushed as far forward as their foodprint will allow often times because the advantage in firing arc is readily apparent for direct fire weapons, and it also reduces the transmission of vibration from firing from some of the more sensitive systems in the superstructure.
4.) There really is very little stability difference between the tip of the bow and some main gun placement like the LCS-2s 57mm that is only twelve meters aft of that. I have acknowledged that there is more instability there, but its not what you think. If you were to take a 5 degrees (that is a lot) pitch the Ml110 on my design will move two meters up, the bow weapon four. Yaw is not a real concern for vessels moving forward, and roll is going to be shared equally by ever mount on that deck. If stability were really an issue then all the calls for me to elevate the weapon the superstructe would not make sense as you take a lot more roll than pitch and the higher you are the greater the effect of roll on stability.
Thats just a few things. There are pros and cons. This is a new concept, blanketly applying the rules of other weapons because that is how its always done is not a good route to go.
