-----Open Transmission to All Nations-----

In a national project, we are planning on upgrading our current coastal defense systems. We are mostly looking to have a reliance on cannons and artillery, as much of our coast is sheltered by geography.

Please, if you would all post your suggestions, I will gladly take them in.

OOC: I am a modern-tech / near-future tech nation

When you say sheltered by geography, do you mean mountains, is it very rocky, steep cliffs, you need to be more specific.

Shore guns and artillery?

It's all a bit Navarone, isn't it?

These days, a couple of SSGNs with really good stand off weapons can deliver accurate and massive destruction on static defenses, rendering them little more than expensive targets.

As a variety of conflicts have shown, if the enemy is dumb enough to run up to your shoreline with lots of ships, your best bet is to hit him and hurt him a lot with standoff anti-shipping weapons. If he's smart enough to use SSGNs or variants thereof, you need to hunt them down and kill them.

Might we recommend, therefore, that you adopt a flexible and mobile approach to coastal defence?

Now...since you want to be able to take out Tomahawks and other Cruisealikes...we recommend this:

Fencer Air Defense System

http://www.mindspew.com/durtistan/Fencer.jpg

Fencer was developed in response to a requirement to defend against low level, agile and fast to supersonic air threats. This specification covers cruise missiles, rotorcraft, unmanned ariel vehicles and low level strike aircraft.
The criteria were: ease of transport, rapid deployment, all round coverage, fast threat response. We believe that Fencer meets and exceeds these criteria.

Fencer can be towed behind medium vehicles or most APCs or deployed by helicopter.
It can be set up by two men in around five minutes. A complete 8 missile reload can be untertaken in two minutes.
Fencer is mounted on a rotatable turret, giving 360 degree coverage.
The total time from target intercept to launch is around five seconds, with second target engagement in three seconds.

Fencer's warhead is a high explosive fragmentation payload triggered by a multi-mode laser proximity fuse. The guidance system is automatic infrared and radar command to line of sight.

The technical radar stats are listed below, but it is worth mentioning that this system was created with stealthy targets and electronic warfare in mind.

The Main Gauche target acquisition and surveillance radar is a multi-beam high resolution 3D radar supplied by Aiglos Systems. The radar is a frequency agile 3D pulse Doppler radar operating in J-band, with scan rate of 60 or 30rpm. The maximum detection range of the radar is in excess of 15km. An optional range of 32km is available. The maximum elevation is 5km. The system has the processing capacity to detect more than 75 threats per second. The radar provides bearing data and threat assessment from a Condor Mark 10 or 12 IFF (Identification Friend or Foe) system. The signal processing system incorporates clutter rejection algorithms and is also resistant to electronic countermeasures. A high elevation guard beam automatically switches off the transmissions when the presence of an anti-radiation missile is detected.

The Zen tracking radar, also supplied by Aiglos Systems, is a differential monopulse frequency agile radar operating at F-band which provides fully automatic all-weather engagement to a range of 15km. The output is sufficiently powerful to burn through most jamming signals and the radar uses advanced frequency management techniques to evade jamming and other hostile electronic countermeasures. The system incorporates a self-surveillance reversionary mode of operation. A dedicated missile command link provides dual firing capability.

The electro-optic tracking device, a passive infra-red electro-optic sensor, is mounted on the top of the turret in a spherical housing and is controlled by an operator at a weapon control terminal. The tracking device can be used in scanning mode to provide passive target detection and acquisition in radar-silent operations. It is also compatible with CLAWS.

We are pleased to note that in tests, Fencer tracked and engaged an F-117A leading to a simulated kill. We look forward to seeing this unit in action against other stealth aircraft.

It's not enough to stop a Cruise - you want to hit the launch platform too. So go find them with:

ARTEMIS Maritime Reconaissance Aircraft

http://www.mindspew.com/durtistan/artemismra.jpg

Artemis has a Searchwater 2000MR multi-mode pulse Doppler search radar from Aiglos Systems and an EOSDS electro-optical surveillance and detection system, supplied by E-KOR and turret-mounted under the nose. The aircraft is also equipped with a radar warning receiver, a Critical Faculty electronic support measures system and magnetic anomaly detector (MAD) system.

In addition to these, the aircraft has a stores management system which carries out inventory tracking and control, air-to-air and air-to-sea weapon control, and built-in test and fault diagnostics.

The aircraft has a weapons bay with side opening doors at the bottom of the fuselage which can carry fuel tanks, torpedoes and sonobuoys. The wings have two additional hardpoints, providing four weapons pylons for the carriage of the AGM-84 Harpoon anti-ship missiles or AIM-9 Sidewinder air-to-air missiles.

The unit is equipped with Basilisk DIRCM as standard.

Just two products for your consideration.

Well ground side mobile artillery units can be more useful in certain situations agaisnt sea borne forces.
Crookfur arms are currently working on 2 highly mobile dfense solutions:
TOaT/T: Tomahawk on a truck/tank, basically a mobile launcher for tomahawk or simialr criuse missile (totlaly moderntech, the US were developing but cancelled a similar idea after agreeing battlefeild nuclear weapon restrictions). basically designed to give greater rnage and punch over existing mobile ASM systems.
Alternatively we are working on integrating our 160mm Naval ETC gun into a heavy truck bed to provide a system simialr to the soviet mobile 130mm naval gun system.

If you would be interested in seeing eother idea developed please give us a shout.
