Oerlikon, now a subsidiary of Rheinmetall, builds a self contained, quick firing, 35mm quick firing revolver cannon for shipboard and land base defense. It is a different concept than the standard Phalanx gun used by Allied navies. The 4 chamber revolving belt-fed cannon is more akin to a giant automatic shotgun, than a Gatling gun.
To be sure, hitting missiles that are homing in on your ship is a daunting task. In order to have time to track, identify and hit something that looks like a baseball bat flying 3000 mph you almost have to give up human control, and artificial intelligence is being prepped for the task. Oerlikon, however, has been building anti-aircraft guns for quite a long time, and their solution is a bit different.
The heart of the gun is it's ammunition. The Millennium can fire many different types of ammunition, in order to counter any number of threats, but the Ahead round is the most interesting. Not only can it counter ship killing missiles, but is also effective against land attacks by rocket, artillery or mortar shells. The round is pre-fragmented, and is programmed as it leaves the barrel to separate into 152 spin-stabilized tungsten fragments at the optimum time into the target path of the incoming threat. In less than a second, from 18 to 24 rounds are grouped together forming a metallic cloud that the threat is not likely to survive.
And in the sales pitch, the whole thing is self contained in an easily installed turret. All you need to feed it is electricity to charge it's batteries, a radar input and someone to say "fire!", and you are ready to go.

The last remaining DO-17 buried in the Goodwin Sands off Deal in the UK is due to be brought up from the deep in May 2013. The RAF Museum in Hendon has finished plans for bringing the craft up in one piece. After that, the important work starts, that of stabilizing the aluminum and steel machine that had been laying in salt water for 70 years.
The Imperial College Metallurgy Department donated the time for testing and developing a solution that would stabilise the metal fuselage and remove all traces of chloride, and in this day and age, also be environmentally friendly. When this aircraft was built, it was only meant to last for a specific time, and in practice they didn't last long at all, with the RAF hell bent on destroying them. After the war, they couldn't be scrapped fast enough, such that sometimes airframes were just piled up and set alight to get rid of them. Now it is a different time, and many people want to see what's left preserved, if only to see what their grandpa flew in during the war. You can also donate to the project.
Dornier was one hell of a company. Started in the 20's, it was famous for it's flying boats. It survived WW2 and made many successful designs, but withered away in the 90's, being absorbed in many companies, one of which was Fairchild aircraft, builder of the Flying Boxcar and the A10 Warthog. Fairchild has since been absorbed by another company and no Dornier designs are being produced by them. Parts of it's accomplishments live on in medical technology, and one company still manufacturers a seaplane, the Dornier Sea Star.

A child born across the river from Cincinnati in 1860 would grow up to invent the original subgun, the Thompson submachine gun. He was born in Southgate House, a hopping music venue and bar in Newport Ky. Check out the Cincinnati.com story.
The submachine gun was invented in the ashes of the First World War, and came to late to revolutionize warfare. For close in work, whether the jungles or WW2 cityscapes, the Tommy Gun beat longer range rifles hands down. British Commandoes couldn't get enough of them, and during continental raids, the .45 caliber lump of lead would usually settle things.
The gun was not an overnight success though, most conservative militaries were drawing down after the Great War and didn't have budgets that would include innovative weapons. In desperation, submachine guns like Thompson's would be marketed to farmers for pest control.
In the 20's and 30's, gangsters did take to them, and the police had to respond in kind. During that time period, there were a number of shoot outs with machine guns around the Cincinnati area. Newport was a big mob town through the '50's and 60's. The last shootout in which Cincinnati Police armed with Thompsons was 1957 with safecrackers in Anderson Township, a local sleepy suburb.
Even during the Vietnam War, the CIA carried Thompson's. They are a bit heavy, but they are every bit as useful today as they were in the past.

New Zealand Mossie back to life, with a little flight with some friends, a Spit and a Vampire. In order to get the shots, they were flying pretty slow, the low throttle indicators were going off a lot. Looks good full screen. Nice way to spend an afternoon.... from Gavin Conroy's channel.

The US Military and Darpa are working on a replacement for the Harpoon anti-ship missile. The intention is a active and passive equipped airborne cruise missile that will go after any target anywhere, without being dependent on communications with home base or GPS. It is also necessary to survive entry into the target area, and also be able to decide for itself where the most lethal point of the target is, and then hit it.
The Harpoon is around 40 years old now, but is no slouch. Originally developed as an open sea anti-ship weapon, it can now be fired from ship, sub or aircraft, at land or sea targets as a surgical strike weapon. It's newest variant, the SLAM ER, for 'Standoff Land Attack Missile, Expanded Response', adds a man in the loop and makes the missile reprogrammable in flight.
The Harpoon's survivability in the current climate of sophisticated ship defenses depends on being networked, being able to see GPS and other overhead targeting satellites and drones. Multiple missile launches are also necessary to ensure one gets through to the target. This is what DARPA wants to solve.
The newest project, the LRASM, 'Long Range Anti-Ship Missile, aims to do away with any dependence on communications, or any outside guidance at all. The missile will be using AI and computer algorithms to guide itself to the target, and choose where to hit it, with no outside interference, especially from the target's assets. A supersonic version was dropped to concentrate on the subsonic version. The sensor packages provided by Lockheed Martin and BAE have been tested, and the airframe should fly early in 2013.
