I've done the same myself in the past.

Here’s something of interest I think y’all will enjoy.
The bofors 40 and 57mm guns can penetrate more than 6” of armor…not sure when that capability will be necessary though lol

Naval 40mm Bofors guns don't use the APFSDS-Tround cited here. That round was developed for antiarmor use in the CV9040 IFV.

It's not clear whether there even is an equivalent round for 57mm Bofors, since there are no current ground applications of that gun. There was apparently some sort of APDS or APFSDS for the German Begleitpanzer support tank (if War Thunder players are any guide) but it very likely is not available today.

Well I can tell you that the 57mm does in fact have that capability. As per former Weps on a freedom.

VLS stack?

Your source is telling sea stories, I suspect. The Navy's budget docs talk about procurement of the 4G bolt guided round (ALaMO), prox-fuzed HE (the 3P round), an HE-PD (point-detonating) round, TP (training), and dummy rounds. No sabot.

3P has an armor penetration mode…it’s literally on BAE’s page for the 3P ammunition. The amount of penetration just isn’t listed

Maybe the Russian VLS is a bit more heavily protected, but I don’t think that’s necessary for ours.

As I understand it, our VLS is designed to hold in explosions, rather than keep out projectiles.

But I was a round barrel guy, not square barrel so no clue about that.

The value in the slide you uploaded and called out is specifically for a tungsten AP sabot round. It has zero relevance to 3P penetration.

A 57mm 3P round isn't going to get through 6 inches of RHA, even in AP mode. The original 57mm SAP would penetrate about 2 cm; 3P maybe a bit more but absolutely not 15 cm.

You can believe it or not, no skin off my back.

Not my fault you don't know what you're talking about about.

To reiterate, there is no US Navy 57mm round that will penetrate 150mm of armor plate. Which is fine because there is also no actual need for a naval round that can penetrate 150mm of armor.
