I haven't been a GM for about 8 years, but I like to keep up on the new stuff. So my question is central to the new 57mm. I understand that the new gun utilizes a dual hoist mechanism to transport rounds from the magizine into the gun mount (I got that from BAE's website), allowing 2-different types of ammo to be used at the flip of a switch (or press of a button). Is this nessesary with the 3-P ammunition that's currently available?

Brian,

There is also some BL&P type rounds, that will be part of the ships NCEA. Cheaper to shoot!

Mk 295 Mod 0 (3P) HE Ammunition is a warshot/tactical round.

Mk 296 Mod 0 (TP) is an inert round that can be used for training, warning/disabling fire and, to a limited effect, surface harassment.

The mount can hold both types in the upper loading system and switch between right & left upper magazines.

TP is similar, but not exactly like the Blind Loaded & Plugged (BL&P) types of round currently in use. BL&P is an actual warshot shell(interior of the shell is scored for fragmenting) with an inert (blind load) and a provision for a fuze. A solid nose is used in place of a fuze. The BL&P round can have a tracer in place of the plug (base). In time of need, the nose & inert filling can be removed and an explosive fill & fuze can be added.

TP rounds are designed to be a near ballistics matched to their warshot counterparts and cannot be re-filled. The interior fill of the round is balanced for a stable flight.

BAE's description of 3P:

Mk 295 3P

There are additional 57mm rounds available from a number of sources, SNC Tec of Canada (GD-OTS)& NAMMO.

There's currently a Federal Business Opportunity (FEDBIZOP) for alternate types of 57mm Ammo:

quote:

The Naval Surface Warfare Center Dahlgren Division is interested in existing non-developmental or near term developmental ammunition technology that can provide Anti-Surface Warfare (ASUW) and Anti-Air Warfare (AAW) for to the 57mm MK110 MOD 0 gun mount and associated fire control systems. The ammunition technology may be sub-caliber or full caliber, fuzed or unfuzed but should provide minimal time of flight, minimal susceptibility to range meteorological conditions, protection against ECM, lethality against small boat to missile patrol boat size threat craft as well as threat fixed and rotary wing aircraft.

To all,
Sorry I do not know how to post a pic so you will just have to go to this website.
