Exercise Joint Warrior


Recommended Posts





“Provide a joint, multi-threat environment in which United Republic of Ireland and Japanese units and their staffs may undertake collective training and pre-deployment training in tactical formations in order to facilitate better defensive initiatives.”



The JW includes between 20 and 30 Naval participants, including aviation, surface and sub-surface units. In addition over 130 fixed-wing aircraft will participate, representing a wide variety of air power capabilities including fast air, Intelligence Surveillance Target Acquisition and Reconnaissance (ISTAR), Maritime Patrol Aircraft (MPA) and Command and Control (C2) assets flying at a daily rate of approximately 100 sorties. Ground based air defence (GBAD) units are also regular participants.


Exercise Area

JW can, if required, utilize the whole of the United Republic including the surrounding seas and airspace.

Maritime play will be concentrated off the NE of Scotland where a freedom to maneuver in both deep and shallow water, coupled with a limited civilian population, air and sea traffic offers excellent training opportunities.

Other influencing factors include access to the weapons ranges around the coast of Scotland as well as other bespoke areas for Naval Gunfire Support (NGS) and Close Air Support (CAS).

Air participants have access to the overland flying areas throughout the UR such as Spadeadam Electronic Warfare Training Range, and oversea training areas including 2 large Fast Jet Areas (FJAs) for air-to-air training off the North and West coasts of Scotland.



The JW participants will travel to Naval Station Portsmouth. From there the participants will travel to the Doggerbank, and then up towards Shetlands. After completing several exercises there, the participants will then travel to about 50-65 miles NW of Shetlands. There is potential for these plans to change, especially locations.





Regional governments and military commands would be notified of naval exercises being conducted by the Irish and Japanese Navies in and around the North Sea.

To participate in the maneuvers, the whole First Fleet, also colloquially called the Combined Fleet (though the term strictly speaking would also have to include naval units stationed in Japan), would be sent from Vitória to Portsmouth. The newly commissioned Mutsu would be added, to assist in the naval gunfire support role, with her heavy artillery, to support the simulated landings of the marine forces of both countries.


The Fleet composition would be as follows:


First Fleet (Command: Admiral Nishi Wakatake)


First Carrier Division

  • Soryū (3 Attack Squadrons, 12 F-4 fighters each)
  • Hiryū (3 Attack Squadrons, 12 F-4 fighters each)

First Battle Division

  • Mutsu (1 Reconnaissance Squadron, 8 drones)
  • Myōkō (1 Reconnaissance Squadron, 8 drones)
  • Chōkai (1 Reconnaissance squadron, 8 drones)

Fifth Destroyer Division

  • Mogami (1 Reconnaissance Squadron, 12 drones)
  • Yūbari
  • Natori
  • Kiso

Sixth Destroyer Division

  • Suzuya (1 Reconnaissance Squadron, 12 drones)
  • Abukuma
  • Chikuma
  • Agano

Expeditionary Division

  • Rishiri
  • Sado


  • Hachirō
  • Akkeshi

1st and 2nd Company, 1st Kaigun Rikusentai

OOC Sorry, will be my one post

The Norse Naval assets in the vicinity would alter their patrol patterns to remove themselves from the vicinity of the exercises as well as notifying both the Irish and Japanese fleets of the change in course and the co-ordinates of the relocated patrol zone to avoid any miscommunication and accidents.

ADM Josue Marty would meet the commander of the First Fleet at Naval Station Portsmouth. They would review all the planned exercises and events and make any last minute corrections. Once all these have been completed both fleets would set sail for the first destination, Doggerbank.

As the ships arrived at the Doggerbank, in formation and constantly surrounded by patrolling fighters and Fuji Neptune II recon drones, the whole fleet would make a turn northward, sailing towards the Shetland islands. Constantly keeping its vigil, the fleet would make no greater offensive postures and just watch assets in the region.

Once the Irish and Japanese fleets were in range of the Shetland islands, ADM Josue Marty would order marine units to prepare for an amphibious landing on the southern shores. INS Challenger would deploy 1000 Marines with AA1 and Terrex ICV vehicles via Landing Craft Air Cushion (LCAC). An additional 1000 Marines from INS Dublin would be flown in via ROTO-22 and HELO-53E aircraft. 5 DX-47B aerial drones would be deployed from INS Dublin to conduct forward reconnaissance for the Marines on the ground. A squadron of 12 F-35C would provide air cover and CAS. NAV2s would provide AWAC for the F-35Cs.


Once all 2000 Marines were on shore, they would push north gaining control of the various islands and roadways. Marine units would also begin to call in Naval Gun Support to destroy designated targets in the water, east of the Bound Skerry.

To "assist" the Irish "landing", the Japanese carriers would launch two wings of aircraft which were to simulate an attack on the enemy's air defenses and anti-ship missile emplacements, before the battle divisions started to get closer and lay down a hail of shells. Instead of targetting the small isles, the fire would be directed only at nearby targets in the water, to measure accuracy, time from request to impact and as an effort to not needlessly crater the island.Targetting would be provided by special reconnaissance drones, launched from Mutsu. Information gathered via the large network of ships, manned and unmanned aircraft would be filtered for valuable information and passed to the Irish for the duration of the exercises. In this way, the Kaigun would also gather expertise in cooperating with forces not linked to the Japanese datalink network.


Destroyers would meanwhile patrol the area guarding the fleet against the ever-present threat from below the surface. Using hull-mounted sonar and SH-60 ASW helicopters, they would thoroughly skim the waters around the isles, though it was still noted that a real threat would most likely be much harder to fight.


Once done, the fleet would pack up and travel towards Scapa Flow, to celebrate the successful exercise.

Once the exercises were complete, both fleets would head towards Scapa Flow to celebrate the successful completion of Exercise Joint Warrior. ADM Josue Marty would address the naval officers of both fleets,


"My fellow officers, ladies and gentlemen,


It is my distinct honor to close the first naval exercises conducted by the Irish Navy in collaboration with the Japanese 1st Fleet. It is in my opinion that both navies learned a great deal and experienced bilateral military cooperation. As we are all very aware, there is a growing national security threat in Europe to the United Republic and many nations abroad. We will not enter the war as an aggressor, however as many times stated before we are fully willing to defend our nation and its people from any acts of aggression by a foreign power. These exercises have shown the ability of the Irish Navy and Marine Corps to successfully conduct amphibious landings and naval air operations with our Japanese counterparts. I personally look forward to working with the Japanese in the near future."


After finishing his short speech, he would offer the mic to the Commander of the Japanese 1st Fleet.




ADM Josue Marty, Admiral of the Irish Navy

Nishi Wakatake would politely nod to express his thanks to the Admiral, before adressing the soldiers present in English.


"Fellow officers, Irish and Japanese,


The exercises come to a close and I think we can all be proud of our achievements today and I'd hope our Irish friends can see this as as valuable a lesson as we do. Despite the Empire's vigilance, the world still is an unruly and dangerous place. The conflict in Europe is nothing surprising, but it still is a murderous affair and we hope these exercises not only have taught both sides well in cooperation, but have also shown to Ireland and the world, that the Japanese Empire stands committed to their allies. Hopefully, there will be more exercises in the future and may those seeking harm for Ireland stay away."


The fleet would still stay for a bit in Scapa Flow, though a return to Japan was considered, due to a few technical difficulties encountered during the exercises.
