Pakistan Navy orders second Kelvin Hughes radar for submarine upgrades

[Zarvan]

The Pakistan Navy has awarded Kelvin Hughes another contract for the delivery of a SharpEye Doppler submarine radar system.

The order follows an earlier one, announced in February this year, and is part of the mid-life upgrade program of the Pakistan Navy’s Agosta 90B-class (also known as the Khalid class diesel electric attack submarines).

Working with Turkish defence contractor STM, the main contractor for the refurbishment program, Kelvin Hughes will supply the SharpEye system to the first submarine in 2018 and the second in 2019.

The upgrades are being performed at the Karachi Pakistan Naval Shipyard however specific details concerning each submarine in the program have not been disclosed.

The SharpEye I-Band (X-Band) radar transceiver for submarines is based on a downmast transceiver housed in an enclosure located within the pressure hull. The radar solution makes use of the existing bulkhead infrastructure in the pressure hull, removing the need to replace the antenna mast system by utilising the existing external antenna, rotational drive and waveguide connections.

Kelvin Hughes also manufactures and supplies a pressure resistant ‘AZL’ submarine antenna.

“We have a long standing relationship with the Pakistan Navy and STM and I am very pleased to be working with STM to supply the state-of-the-art SharpEye radar system to the Khalid class submarines,” Barry Jones, regional sales manager for Kelvin Hughes, commented.

Looks like pn likes stm work as originally it was one plus 2 meaning 2 were follow on once first sub was mlu successfully 2 and third would have been added to the order

can anyone elaborate what is the benefit of this upgrade in layman terms???

@Rashid Mahmood and @fatman17 can do it

 

[Rashid Mahmood]

It's an upgrade of the previous radar system on the 90Bs.
The benefit is that it needs no major mod, and uses the same external antenna as the previous.

The detailed specs of the radar would be available on the KH website.

Pakistan orders SharpEye radar for second Agosta 90B submarine

The U.K.-based navigation, surveillance and security radar systems supplier Kelvin Hughes announced that it has received a new order from thethe Pakistan Navy for the SharpEye Doppler radar.

This unit is slotted to equip the second Khalid-class Agosta 90B air-independent propulsion (AIP)-equipped submarine, the PNS Saad, in 2019 under a mid-life upgrade program. Kelvin Hughes will supply the radar for PNS Khalid in 2018.

The SharpEye is a low probability-of-intercept (LPI) radar with a sub-clutter visibility (SCV) of 30 dB. It can track targets as small as 0.5 m2 RCS (radar cross-section).

Kelvin Hughes states that the SharpEye is an effective upgrade solution as it can utilize “existing bulkhead infrastructure in the pressure hull,” negating the need to change an older submarine’s “external antenna, rotational drive and waveguide connections.”

The Pakistan Navy had also selected the SharpEye I and E/F-band radar (along with support equipment, such as tactical radar software) for its forthcoming 17,000 Fleet Tanker (currently undergoing sea trials).

Kelvin Hughes states, “The combined systems will equip the vessel with warship navigation and tactical situational awareness capabilities, including helicopter tracking, recovery and control.”

Notes & Comments:

In 2016, Pakistan awarded the Turkish defence contractor Savunma Teknolojileri Mühendislik A.Ş. (STM) the contract to upgrade the Agosta 90B AIP submarines. The lead ship – PNS Khalid – was earmarked for delivery in 45 months and the subsequent two were follow 12 months of one another. STM is the prime contractor for the program, which is being implemented at Karachi Shipyard & Engineering Works.

Kelvin Hughes was acquired by the German electronics company Hensoldt in June (concluded in October). Hensoldt was formed by the private equity group KKR, which had acquired two divisions from European defence giant Airbus Defence & Space (Airbus DS): Airbus DS Electronics and Border Security GmBH and Airbus DS Optronics GmBH. The latter – now known as Hensoldt Optronics South Africa (HOSA) – will supply SERO 250 periscopes and OMS 200 optronic masts for the Agosta 90B upgrade.

The Turkish companies Aselsan and Havelsan are also subsystem suppliers in the program, providing the ARES-2SC/NS electronic support measures system and Naval Integration Command and Control System, respectively. STM and the Pakistan Navy have yet to announce a replacement for the Agosta 90B’s sonar system, which is currently the Thales TSM 223. It is unclear if all subsystems will be replaced.

They're basically fitting the Agosta 90B with the sort of subsystems (e.g. radar, CMS, ESM, etc) you'd find on newer designs such as the Scorpene and Type 214. Benefits could include greater automation, more effective sensors for ELINT/ISR, etc.

What capabilities it add over previous one and after upgrade where A90s will stand compared to Indian advance subs and ASW capabilities?

Will upgrade allow A90s to face newer IN subs, ASW and P-8s??

It'd be in a better position to do so than it is now.

PN subs must have advance capabilities to detect and engage airborne threats at distance, we need 50km range Sub launched SAM for our subs.
