IJN (wargame)
From Wikipedia, the free encyclopedia
IJN (Imperial Japanese Navy), subtitled "A Tactical Game of Naval and Naval-Air Combat in The Pacific, 1941–1945," is a board wargame published by Simulations Canada in 1978 that simulates various naval encounters during the Pacific Campaign of World War II. It was the first in a series of three interlocking naval wargames.
Scenarios
IJN is a two-person wargame of search followed by combat. It is played on a large featureless hex grid map where each hex represents 100 yards (91 metres), and each turn represents 90 seconds of game time.[1]: 17
Scenarios vary from two-ship engagements to large fleet battles. In each case either destroyers or airplanes search for enemy ships. When the enemy is located, larger ships, possibly accompanied by bomber aircraft, move in to engage in battle.
Movement of both players is simultaneous, with each player preplotting their movement for the turn, and then revealing them at the same time. The turn then takes the following sequence, all done simultaneously for both players:
- Search
- Gunfire
- Ship Movement
- Aircraft Movement and Bombing
- Torpedo launching and movement (Torpedo movement is logged secretly until the torpedo is placed on the map when it is one hex from its target. Before it is revealed, the targeted ship has a chance to spot the incoming torpedo and take evasive action if possible.)
The game comes with the following scenarios:
- Battle of Balikpapan
- Battle of the Java Sea
- Battle of Sunda Strait
- Destruction of the Exeter
- Battle of Coral Sea (5 separate scenarios)
- Battle of Midway (8 separate scenarios)
- Battle of Savo Island
- Battle of Lunga Point
- Battle off Samar (a series of four hypothetical scenarios)
- Battle of Cape Esperance
- Battle of Kula Gulf
- Battle of Suriago Strait (3 separate scenarios)
Extra counters are included in the game to allow the players to design their own scenarios.
