Additional information regarding the modernization of Nigerian navy’s flagship NNS
Aradu has emerged. NNS Aradu which is a Meko 360 class frigate designed by the German
Blohm + Voss company of Hamburg in 1980 is to be refurbished and modernized by [Turkish Dearsan Shipyard in a contract signed in may this year.](https://www.military.africa/2023/05/nigerian-navy-strengthens-frigate-capacity/)

Tahir Conka, the Business Fevelopment Manager at Dearsan Shipyard at the IDEF 2023
defence exhibition in Turkey ccommented on the planned modernization project for
the nigerian navy’s flagship NNS aradu.

In May this year, it was revealed during the Presidential Fleet Review 2023, that
the NNS Aradu will be taken to Istanbul, Turkey for refit and returned within 24
months.

Tahir Conka revealed recently at the IDEF 2023 that the NNS Aradu’s navigation, 
communications, sensors, and electro-optical suite will be modernized. While the
combat system will be partially replaced. Also the 40 mm guns will be replaced with
a newer more modern variant. The ship’s hull which was scanned by Dearsan and found
to be defective due to age will be strenghtened.

The Meko 360 class frigate, NNS Aradu, has served as a flagship vessel for the Nigerian
Navy for several decades, playing a crucial role in safeguarding the nation’s maritime
interests and contributing to regional stability.

NNS Aradu started her life as ‘The Republic’, laid down at the Blohm Voss shipyard
in Hamburg on December 1, 1978, and launched on January 25, 1980, two years later.

At her prime, NNS Aradu was capable of being armed with a wide range of armaments
including anti-ship and anti-air missiles, anti-submarine torpedoes and rockets,
as well as powerful naval guns.

With the age and obsolescence of her major weapons, sensors, and combat systems 
the ship was to undertake a new role as a combat training and offshore patrol ship.

Aradu’s main gun is an OTO Melara Compact 127 mm/L54 dual-purpose gun. It fires 
31 kg projectiles at up to 40 rounds/minute, out to a maximum range of 23,130 m 
and an anti-aircraft ceiling of 7 000 m. Capable of engaging ships, land targets,
aircraft, and even some anti-ship missiles.

For air defense, it was armed with four Breda “Twin Fast Forty” CIWS turrets, each
with two Bofors 40 mm/L70 automatic cannons, with one mounted at the four corners
of the ship.

Each turret fires a 2.5 kg projectile at up to 900 rounds/minute out to a maximum
range of 12 500 m and an anti-aircraft ceiling of 8 700 m.

These anti-aircraft guns is capable of destroying a supersonic cruise missile at
up to three kilometers.

To complement the anti-aircraft guns, an Albatross surface to air missile system
was mounted in an octuple launcher atop the hangar. The Albatross SAM is a variant
of the United States Raytheon RIM-7 Sea Sparrow.

To combat enemy ships, the NNS Aradu is armed with eight Otomat Mk 1 anti-ship missiles
carried amidships with four situated behind the mast and forward the twin funnels
and two each amidships on each side of the ship.

The Otomat Mk 1 is a short-range subsonic anti-ship missile developed by the Italian
company Oto Melara jointly with Matra. It is capable of reaching around 180 kilometres
at an average speed of 1,100 kilometres per hour.

It is not yet certain if new missile systems will be fitted onboard NNS Aradu. The
old stock of Albatross SAM and Otomat Mk 1 anti-ship missile has since been destroyed
by the Nigerian Navy due to its age.

Other equipment and weapons carried includes a 6 x 324 mm torpedoes and a depth 
charge rack. Both are for anti-submarine warfare. An ECM suite is fitted, with a
Decca RDL-2 ESM system, and two chaff mortars. Aradu is equipped with Plessey AWS
5 air/surface search radar, Racal Decca 1226 navigation radar, Signaal STIR and 
WM 25 fire control radar and Atlas Elektronik hull-mounted sonar. The ship originally
mounted PHS 32 sonar, but this was later replaced. The frigate mounts two chaff 
dispensers and Decca RDL-2 electronic support measures. The ship has a hangar and
flight deck capable of operation two helicopters of the Westland Lynx Mk.89 type,
but usually only carries one. The vessel has a complement of 195, including 26 officers.

For propulsion, the ship is powered by a CODOG system made up of two Rolls-Royce
Olympus TM3B gas turbines rated at 50,000 shaft horsepower (37,000 kW) giving the
ship a maximum speed of 30.5 knots (56.5 km/h; 35.1 mph) during use and two MTU 
Type V 956 TH92 diesel engines rated at 10,420 brake horsepower (7,770 kW) with 
a maximum speed of 18 knots (33 km/h; 21 mph) under use. The engines turn two Kamewa
controllable pitch propellers and the vessel carries 440 long tons (450 t) of fuel.
This gives the frigate a range of 6,500 nautical miles (12,000 km; 7,500 mi) at 
15 knots (28 km/h; 17 mph), with an endurance of 90 days.

Since 2010, Aradu (Hausa for “Thunder”) has been [inoperable](https://www.military.africa/2019/11/how-africas-most-powerful-warship-became-a-floating-wreck/)
for due to lack of funding. However, in February 2020, the [frigate underwent refit at the Naval Dockyard limited](https://www.military.africa/2020/07/nigerias-thunder-fights-again/military.africa/2020/02/nns-aradu-nigerias-most-powerful-warship-gets-a-refit?v=65d8f7baa677)
in Victoria Island, Lagos. By September that year, [NNS Aradu sailed again](https://www.military.africa/2020/07/nigerias-thunder-fights-again/)
albeit under the for the first time in several years.

Dearsan has also signed a contract with nigeria to supply two offshore patrol vessels,
as well as a [57-meter Tuzla patrol boat](https://www.military.africa/2023/05/nigerian-navy-strengthens-frigate-capacity/).
The Nigerian Navy’s [newly acquired Tuzla patrol boat](https://www.military.africa/2023/06/turkish-dearsan-shipyard-to-supply-57-m-tuzla-class-patrol-boat-to-nigeria/?amp=1)
built by Dearsan Shipyards in Turkey will be fitted with a [more reduced armament](https://www.military.africa/2023/08/nigerias-tuzla-class-warship-fitted-with-reduced-armament/)
load out to reflect it’s role as an offshore patrol vessel.

The OPVs are being constructed as part of a contract signed between Dearsan and 
the Nigerian Navy In August, 2021. the Nigerian Navy (NN) announced its intention
to procure [two new offshore patrol vessels (OPV)](https://www.military.africa/2021/11/more-details-emerges-on-nigerias-new-turkish-opvs/),
after it received approval from the former President Muhammadu Buhari.

Turkish DEARSAN Shipyard officially [started the construction of two OPV-76](https://www.military.africa/2022/09/dearsan-begins-construction-of-nigerian-navys-opv-76-warship/)
Offshore Patrol Vessels for the Nigerian Navy with a keel laying ceremony held on
September 16, 2022. OPV-76 ships will be fitted with [four MAN product diesel engines (18VP185)](https://www.military.africa/2021/03/man-engines-to-power-west-african-naval-vessels/),
and it is stated that the vessels can reach a maximum speed of 28 knots. Constructed
in line with the Türk Loydu Ship Classification rules, the hulls of OPV-76s will
be made of steel sheets, and marine aluminium (Sealium) will be used in the ship
superstructure. The operational range of the ships is stated as 2.500nm (nautical
miles). A contract was signed with HeliPLAT Co.Ltd. for the certification engineering,
testing, and HAT/SAT activities of the helicopter platform on the OPV-76 ships.

The two new Turkish-built OPV 76 will further enhance Nigeria’s naval capacity currently
served by two P-18N OPVS, two Hamilton-class patrol cutters, a number of fast patrol
missile-boats, and several inshore patrol vessels.

They will be used for maritime interdiction operations, surveillance and special
forces operations as well as providing naval fire support to land forces. “The OPVs
will also be capable of conducting search and rescue operations, anti-piracy, anti-
smuggling and anti-drug trafficking operations and disaster relief operations among
others,” former Chief of Naval Staff Admiral Gambo said.
