Compared with that weapon, the major improvements of the Mark 1 were a higher rate of fire, the use of new munitions including an improved proximity fuse, water cooling for the gun tubes and a new electro-hydraulic system for rapid training and elevation. The Mark 1 was exported to Malaysia and the former Yugoslavia. The Mark 2 was a lighter weight mounting and used a new servo system that reduced aiming errors and damping time. The gun barrel for this mounting used a special monobloc steel that eliminated the water jacket Bofors claimed that this gun was dual-purpose in that it was accurate and agile enough to destroy sea-skimmers and that it could put more explosives into a surface target in thirty seconds than any gun smaller than 10 cm 3.
About 25 Mark 2 guns were manufactured. The Mark 3 is the latest version. This mounting uses the same ammunition as the Mark 2 but also can fire "smart" ammunition. The Mark 3 is offered with an optional low radar profile RCS mounting which hides the gun barrel when not in use. It is claimed that the Mark 3 has a mean time to repair of 30 minutes and can be installed on ships as small as tons mt.
This mounting uses a small radar mounted on the gun barrel to measure muzzle velocity for fire control purposes. The dual-hoist system allows instant switching between ammunition types, but rounds must be removed manually in case of misfire.
This mounting can open fire at 45 degrees training and 35 degrees elevation from the stand-by condition in 2. The mounting is normally remotely controlled, but can be used in a gyro-stabilized local control mode.
This change of designation followed a successful firing test of 29 practice rounds and 26 rounds of 3P service ammunition at the Dahlgren Main Range in Dahlgren, Virginia. The initial test firings were conducted to verify the test range instrumentation and to document the gun system's characteristics for the upcoming Test Readiness Review of the EX Mod 0 gun safety qualification project.
An article by Lt. The test firings have been conducted in three phases to evaluate blast effects, ballistics, and serviceability.
The function of the Mk Naval Gun is to provide key ship self-protection and attack capabilities. As far as maintenance and accuracy of the new weapon, the all-around ability is a lot easier to handle compared to our current armament.
I'll definitely look forward to working on the 57 mm gun. The contract includes options such as spare parts and training.
Typical dispersion of the Mark 3 for elevation s-value is 0. Most rounds have conical or hemispherical base outlines to improve aerodynamics and to maximize the internal volume.Justification as provided to Congress is here. The round is expected to be operational in about the time the first OPC comes out. The 57mm ALaMO funding supports non-recurring engineering, design verification testing, environmental qualification, hazard classification, insensitive munitions and developmental testing.
Sounds like the Coast Guard should have a few of these rounds as well, both for small, fast, highly maneuverable targets, and to target specific areas on larger targets.
We had some indication this was coming before. The new projectile has passed critical design review. You are commenting using your WordPress. You are commenting using your Google account.

Post to Cancel.Production of the baseline 57 mm Mark 1 variant began in and was initially used to equip smaller coastal patrol craft and fast attack craft. The gun is remotely controlled by a fire-control computer; as a redundancy measure, however, the crew can also operate the gun using instrument panels that are either on or in direct contact with the gun.
The gun was upgraded and improved several times, first the Mark 2 in which drastically lowered the weight as well as introduced new servo stabilizers. The Mark 3 came in with modifications made to enable the smart ammunition developed.
However, as jet aircraft became more prevalent in the post-war era, it was clear the gun did not have the rate of fire needed to effectively deal with these threats. Bofors' engineers considered two solutions to the problem. One was to greatly increase the firing speed of the 40 while also incorporating any minor changes that would improve its range. The other was to design a larger weapon with much greater effective range and a larger explosive load that offset a lower firing rate.
With minor modifications, the Mark 1 guns could use ammunition developed for the Mark 2 gun. This new design retained the Mark 2 gun mount, rate of fire and ammunition capacity and has another 1, rounds stowed in the standby rack beneath deck. Also, a new optional low radar profile also known as low radar cross-sectionor RCS stealth mounting was developed, this allows the gun to be hidden from radar and plain sight when not in use. This increases the flexibility and effectiveness of the gun system, which has further reduced the reaction time of the gun and it is possible to choose ammunition mode at the moment of firing, giving it the ability to switch rapidly between surface targets, air targets, and ground targets.
Answering a U. It is fitted with a multi-mode imaging semi-active seeker that can be guided through laser designation or autonomous targeting by downloading image of the target prior to firing; ORKA retains the 3P multiple fuzing modes. In Decemberthe U.
Improvements included a higher rate of fire, the use of new munitions including an improved proximity fuse, water cooling for the gun tubes and a new electro-hydraulic system for rapid training and elevation.
Finland, Malaysia, Norway, Indonesia, Singapore and the former Yugoslavia are among the countries that adopted the Mark 1. The Mark 2 was a lighter weight version, which utilized a new servo system. Bofors designed the gun in and it entered active service on the Stockholm -class corvette in The gun was partly dual-purpose in the sense that it is accurate and agile enough to destroy sea-skimming missiles. Bofors 57 mm Mk 3 on Finnish missile boat Hanko.
The Mark 3 is the latest version of the gun. Bofors designed it in and it entered service in The gun uses smart ammunition but can also fire the same ammunition as the Mk 2. The stealth variant has a reduced radar profile, in part by hiding the gun barrel when it is not firing. Also, the gun has a small radar mounted on the gun barrel to measure muzzle velocity for fire control purposes and can change ammunition types instantly due to a dual-feed system.

Interesting & obscure RAN discussions (not related to current capabilities)
We know Spike missiles can be sea launched and have a range of at least 6km, as documented by the Philippine Navy! In The test took So a simple missile that would just launch, go where it is intended to go, and explode releasing shrapnel.
Wombat Active Member. Spike missiles on ships would be more of a last ditch defence which might not be so bad but it is in no way an offensive weapon when we have to close range so much that you can start yelling insults at one another.
We theoretically have almost the entire industrial and technical capacity and knowledge to build these missiles outside of engines and propellant but to do it in Australia and have it up and running efficiently early on would require us to be doing this before conflict which means more money. To start it up after the fact means a long wait before it makes any difference. Easy enough to want dumb downed missiles but dumb downed missiles tend to only work in large swarm attacks.
So unless money can be found to set such a capability up before hand it is a non starter. Said it before and I stand by it based on current information but our best bet is to increase the lifespan of our munitions thus artificially increasing the stockpile. We need to work within in our regional, size and financial limitations if it doesn't work then we need to adapt.
