OHPs with proper Long to Medium range automated Air defence, having capable long range Antiship and submarine capabilities may prove to be effective like Turkish OHPs not like Pakistani lone OHP having no effective Ammo. Even Pak F22Ps having some stealthiness are handicapped due to limited short range Air defense,
Turkish OHPs (G-class frigates) have undergone a major modernization, with key elements:
- GENESIS advanced combat management system
- 8-cell Mk-41 VLS for Evolved Sea Sparrow, including the upgrade of the Mk-92 fire control system
- new advanced SMART-S Mk2 3D air search radar to replace AN/SPS-49
Note they had a functional Mk13 launcher to begin with (32 SM1 + 8 Harpoon)
Note also that Turkey has not elected to switch to SM2.
Under SEA 1390, the Australian Adelaide Class ships received a modified and re-hosted FFG Naval Combat Data System (NCDS) and Australian Distributed Architecture Combat System (ADACS), operating on upgraded computers with new Q70 consoles, and using an upgraded Local Area Network (LAN) with higher data transmission rates. Link-16 equipment was introduced to complement the older Link-11 standard, and provide the combat system with better allied and helicopter interoperability.
The AN/SPS-49v4 air surveillance radar is upgraded to AN/SPS-49Av1MPU, and the AN/SPS-55 surface search and navigation radar is improved.
The Mk92 Fire Control System is upgraded from the original MOD 2 to MOD 12, which includes upgrades to the Separate Target Illumination Radar (STIR).
An Radamec 2500 EOTS system offers long-range passive TV & infrared surveillance that doesn’t warn its targets, plus a laser rangefinder. It’s integrated into the targeting system, but the RAN has placed operational limitations on it due to performance.
Along related lines, a multi-sensor Radar Integrated Automatic Detect and Track System (RIADT) was added to improve target detection, tracking and engagement, particularly against low altitude targets in cluttered ocean or near-shore environments.
The old AN/SLQ-32v2 “Slick 32” electronic support system was replaced with newer technology from Israel’s Elbit (EA-2118) and RAFAEL (C-Pearl). An ESM system picks up and classifies enemy radar emissions, and part of its role is to act as a 2nd layer of warning against attacks.
The ships’ existing Mk13 GMLS pop-up launcher retains its 40 round magazine, but it can now be fitted for more advanced SM-2 Standard anti-air missiles and Harpoon strike missiles (usually fitted: 32 x SM and 8 x Harpoon). An 8-cell Mk41 tactical-length vertical launching system will generally carry up to 32 shorter-range RIM-162 Evolved Sea Sparrow air defense missiles, but could carry different weapons including SM-1/ SM-2s.
Ships owned by Bahrein (1), Egypt (4), Pakistan (1) Poland (2), Taiwan (8) and Spain (6) have not be so modernized. Some entered current navy service without Stir and Mk13 (Pakistan). Ships leaving USN service haven't had Mk13 / Stir since 2003.
Nothing inhibits the ASW capability of the ship in PN service. It would not be difficult to add Harpoon (see racklaunched HF2 and HF3 on Taiwanese ships). It would not be difficult to add some VLs forward e.g. 3-cell sets with quad packed CAMM (12 missiles), a Sylver A-35 or A-43 with Mica etc. These require no guidance radars. A Mk 48 six pack with 2 ESSM per cell (12 missiles), a mk41 with 32 ESSM would require reinstallation of STIR(s).
I doubt if these old ships are worth that kind of investment for a navy with few of them.
Very succinctly put
@Penguin bhai.
Heavy Armor with thick plate steel is a World War II concept - in the age of High-explosive bunker-busting armor-piercing missiles, having thick plate steel as armor is of almost no use in a ship.
Agree, still ....
Arleigh Burke destroyer design
The entire ship (except the two aluminium funnels) is constructed from steel, with vital areas protected by two layers of steel and 70t of Kevlar armour.
Arleigh Burke Class (Aegis) Destroyer - Naval Technology
The DDG-51 Class ships are specifically constructed from a survivability-enhanced design that affords passive protection to personnel and vital systems. This design provides protection against underwater shock, nuclear air blasts, fragment incursions into vital spaces, radar detection, electronic countermeasures, gun and missile attacks and a Chemical, Biological and Radiological (CBR) attack. A comprehensive Collective Protection System guards against nuclear, chemical, or biological agents. The ship's damage control features and constructional design make the DDG-51 Class Destroyer the most "survivable" surface ship in the world.
In the ARLEIGH BURKE Class, all-steel construction is used. Extensive topside armor is placed around vital combat systems and machinery spaces. The bulkheads are constructed of steel from the waterline to the pilot house. The bulkheads are designed with double-spaced plate construction for fragment protection. The frontal plate causes fragments to break up and the backup plate stops the fragments from causing further damage to the interior of the ship. Other Aegis combat system equipment rooms are protected by Kevlar shielding. And, topside weight is reduced by incorporating an aluminum mast.
Acoustic, infrared, and radar signatures have been reduced, and vital shipboard systems are hardened against electromagnetic pulse and over-pressure damage. Sound isolators or "shock absorbers" have been placed on the reduction gears, giving the ship an added advantage when pursuing submarines. State-of-the-art propulsion and damage control systems are managed by an all-new data multiplexing system. Fire detectors and increased AFFF and Halon protection add to improved survivability.
Ship Info
The George HW Bush has the same new bulbous bow design that was used in the CVN 76 USS Ronald Reagan, commissioned in 2003.
...
Safety features include areas of 6.4cm-thick Kevlar panels over sections of the hull. Other safety and damage control measures include box protection structures over the magazines and machinery spaces, and also full and empty compartments are located at the sides of the ship.
USS George HW Bush (CVN 77) Aircraft Carrier - Naval Technology
Some 130 tons worth, I gather.
I suppose Kevlar does better than steel against semi-armor piercing warheads
