Kelvin Hughes To Supply I-Band SharpEye Submarine Radar Systems To Pakistan

It's not supposed to compete with sonar for detection. It's a navigation radar for maneuvering in confined spaces or congested waters where sonar usage is either restricted (active) or becomes mired in the clutter of coastal waters (passive). Many smaller boats have equally small RCS, hence why the SharpEye's pitch makes note of its ability to detect low RCS vessels, this will help ensure the submarine can safely transit in bottled-up waters or waters with high traffic when on the surface.

Launched in 2006, more than 25 navies now use SharpEye™ radars and displays, which delivers improvements in sub-clutter visibility by approximately 30dB, enabling targets with a low Radar Cross Section (RCS), typically 0.5m2, to be detected even in heavy rain and high sea states. Doppler processing enables clutter removal without picture degradation. This combined with a host of other unique and special features in the radar sensor, provides an unprecedented level of situational awareness.

Note: this does not equal counter-stealth capabilities. The low-RCS detection capability are meant to track small boats like coastal fishing vessels in adverse conditions, not stealthy warships at standoff ranges.

You'll find them on larger vessels too, but again, they don't replace the larger radars like SPY-1F (look atop the SPY-1 mast and below the forward SPG-62)

Smaller boats like RHIBs also have such radars, although in this case the array is static and does not rotate.

It'll make them safer when transiting near-shore waters or moving for sea-to-port or port-to-sea, but it's nothing overly special. Rating it kind of seems unnecessary. It does its job.

The type is already in use on the RN's Type 45 destroyers (look directly above the bridge, almost half-way up the mast).

And if you observe more closely you will find the little triangles in the eye as well, THE PYRAMIDS!!

Speaking of which, when a thread is watched by a member, a similar one eye is observed....Are we compromised? @Arsalan @WebMaster

Illuminati eye was the last thing I expected form PDF. And it appears on every watched thread...

Meanwhile, KH is equally pleased to announce the deal...


Kelvin Hughes is pleased to announce that it has been contracted to supply the I-Band SharpEye™ Doppler submarine radar system as part of a mid-life upgrade program for the Pakistan Navy’s Agosta 90B-class submarines (also known as the Khalid class diesel electric attack submarine).

Working with Turkish defence contractor STM, the main contractor for the refurbishment programme, Kelvin Hughes will supply the SharpEye™ system to the first submarine in 2018.

Traditionally, submarines only tend to use radar for navigation when entering or leaving port, because high-power RF transmissions can compromise their ability to remain undetected when used in more open waters. However, with its low power, pulse Doppler transmission technology, SharpEye™ can provide a reduced probability of intercept which significantly lowers the risk of the submarine being detected but without compromising the target detection performance of the radar.

Featuring high reliability, low maintenance, solid-state technology, the SharpEye™ transceiver can be located within the pressure hull, making use of the existing bulkhead infrastructure, antenna rotational drive and waveguide connections.

Doppler processing of the radar returns means that more targets can be detected, earlier and at a longer range. Delivering improvements in sub-clutter visibility of approximately 30dB, SharpEye™ can identify small, low RCS (Radar Cross Section) targets, even in adverse weather conditions. A series of electronic filters enables SharpEye™ to distinguish between targets of interest and unwanted sea and rain clutter.

Barry Jones, Regional Sales Manager for Kelvin Hughes, commented:
“We are delighted that the Pakistan Navy, a respected and long-standing customer of Kelvin Hughes, has chosen to take advantage of the performance and reliability benefits that our innovative SharpEye™ radar technology can now bring to submarine platforms. We’re looking forward to working with our project partner STM to jointly deliver SharpEye™ capability to the Navy and Khalid Class submarines”.

Earlier this year, Karachi Shipyard & Engineering launched the Pakistan Navy’s 17,000 tonne fleet tanker and Kelvin Hughes can also now announce that it has been contracted to supply the ship with SharpEye™ I and E/F frequency Band Doppler radar as well tactical radar software and widescreen displays. The combined systems will equip the vessel with warship navigation and tactical situational awareness capabilities, including helicopter tracking, recovery and control.

Seems that the only pieces remaining are the sonar and ASW and AShW launch suite. Seeing that STM and the Pakistan Navy have bought systems from Turkey, Germany and UK (and not France), I wonder if they'll pick up the Atlas Elektronik ISUS 100. It's already compatible with the DM2A4 heavyweight torpedo the PN uses.

Man, I really hope they extend the Agosta 90B's new subsystems to the Hangor-class SSPs. We should be able to integrate this stuff at KSEW. I have two wishes for the Hangor-class SSPs: fuel-cell AIP and the same subsystems as the Agosta 90B.

So here is the thing. ISUS system user s also use DM2A4 Torpedoes and at least on the wiki page of the Torpedo Pakistan is mentioned as a user.
The Torpedo is 6.6 meter long.
Most Indians said that Babur cannot be used on Pakistani subs because its longer than Pakistan navy submarine Torpedo tubes. But it's not longer than 6.6 meters the length of this torpedo.
So does that mean PN Agosta always had capability to carry Babur?

On a serious note, i am not sure what additional advantages it will have over the Sonar systems that we have (they are also be upgraded as far as i know)
