File Name: Submarines Galore 2014 !!! File Submitter: broncepulido File Submitted: 18 May 2014 File Category: GIUK Submarines Galore 2014!!!, late May 2014, Alternate history scenario. A Harpoon Commander's Edition scenario for the EC2003 Battle for GIUK Gap Battleset and the HCDB-130818 1980-2015 Era Platform Database. Image from Wikipedia: Portsmouth, Va. - The nations newest and most advanced nuclear-powered attack submarine USS Virginia (SSN 774) passes the skyline of Hampton, Va., with the campus of Hampton University seen in the background, on its the way to Norfolk Naval Shipyard upon completion of Bravo sea trials. Virginia is the Navys only major combatant ready to join the fleet that was designed with the post-Cold War security environment in mind and embodies the war fighting and operational capabilities required to dominate the littorals while maintaining undersea dominance in the open ocean. August 25, 2004. U.S. Navy photo by Journalist 2nd Class Christina M. Shaw(RELEASED). A submarine-only scenario without other diversions, inspired on origin by some old scenario booklets of the Harpoon 3 series but very modified on this 2014 Edition, good for testing submarines (specially the new ones included after HCDB-110831), submarine tactics, sonars, torpedoes and other ASW weapons. Perhaps the Western submarines are numerically over-represented, but it's reflecting the original and very reduced in number of submarines paper scenarios. Also it's configured as a vanilla scenario for lazy players wanting to enjoy a simple pastime, and with the aim of replayability thanks to the aleatority of the starting positions and of the units presence or not presence. I think it's playable at the 10 or even 30 minutes time compression ... before doing any contact. From February 21, 2014, well staged by President Putin, were unveiled and erupted multiple simultaneous crises in Ukraine, Baltic States and China. With a feeble and hesitating Obama Administration, and when the international relations and foreign policy "experts" and "analysts" were expecting for the start of a new cold war, it was very difficult for the uncoordinated and surprised Western Powers to see another path than that of the war. At least the first ten boats of the very advanced Virginia-class SSN were commissioned on less than the programmed budget and even eleven months before the scheduled date. Also, the Russian submarine fleet has not been very updated from the Cold War end, and has substantially shrunken in number. To keep low the political and social unrest because the war imminence and also because exceptionally bad weather, the opening naval actions were limited to discrete submarine operations, in a situation remembrance of the 1939 Phony War and of the 1994 Tom Clancy's novel Debt of Honor (where both Japan and the United States are in war against the other, but both governments are occulting the fact to his respective public opinions to prevent the collapse of the stock markets), but these underwater actions were not less decisive or murderous than a full open war.

File Name: Operation Ivy Bells, 1971. File Submitter: broncepulido File Submitted: 27 Jan 2013 File Category: WestPac Operation Ivy Bells, 1971. The Halibut finest moment. This picture of USS Halibut in San Francisco Bay is a USN official photo apparently in public domain, retrieved from navysource.org, published on that site as courtesy of Darryl Baker. A Harpoon Commander's Edition scenario for the WestPac Battleset and the HCCW-120614 Cold War Platform Database. This scenario is designed for play by the US/Blue or the Soviet/Red side, to avoid spoilers is better to play first some times the US/Blue side and only after play the Soviet/Red side. The noisy and peculiar USS Halibut (originally SSGN-587) was previously a Regulus strategic missile carrier later converted in a apparently conventional SSN, after the Regulus cruise missile was retired and his patrols deleted just some months before the introduction of the SSBN patrols. But Halibut was not a quiet fish. Halibut was converted for special covert operations in the Cold War, exploiding the room of her cavernous hangar, but her conversion and her missions not yet full exposed or detailed (aside this one, Halibut was previously employed on at least another great mission, Operation Sand Dollar, locating on 1968 the accidentally sunken K-129, a Soviet Golf-class SSB, for her ulterior recovery in Project Azorian). The basic design was developed by Dr. John P. Craven head of USN Deep Submergence Systems Project. From summer 1971 she was equipped on the after deck with a fixed divers decompression and lockout chamber simulating a DSRV submersible, for very deep saturation divers breathing an helium and oxygen mixture with methods researched at SeaLab. Operation Ivy Bells was based on the intuition of Captain James E. Bradley Jr. director of undersea warfare at the Office of Naval Intelligence about the existence of a undersea communications and telephone cable in the Sea of Okhotsk between the Soviet SSB/SSBN base at Petropavlosk in the very far and almost isolated Kamchatka Peninsula and his Pacific Fleet Headquarters near Vladivostok. The idea was, one time determined the cable emplacement (and previously guaranteed his existence in the same mission!) to tape it with a device working through induction, without violate physically the cable, and even with the adequate legal converture within the bounds of international law, out of the three mile limit of the Soviet territorial waters. The mission was a complete success, the cable was taped, and the Soviets delivered unencrypted plain text messages by the cable, thinking it was sure. Later, other cables will be taped by other US submarines, but this was the first one. And so, on October 1972, Halibut sailed with her captain Commander John E. Mcnish from Mare Island to hunt the West Shore of the Kamchatka Peninsula with the covert mission of retrieve debris of the SS-N-12 anti-ship missile, but actually after signals of fantasy cables and to an uncertain future. Probably this is not an easy scenario. Enrique Mas,January 2013. Click here to download this file

File Name: Pearl Harbor Midget Submarine Action, Day of Infamy File Submitter: broncepulido File Submitted: 22 Aug 2012 File Category: WestPac Midget Submarine Action in the Pearl Harbor Attack. This scenario is designed to be played from the Japanese/Red side, or the American/Blue side, but is better to play first the Japanese side. The Day of Infamy 7 December 1941 attack on Pearl Harbor is almost only remembered by the Japanese carrier-based air attack, but a very controversial, analysed and with few results midget submarine attack was in course a few hours earlier, and it was near to denial the surprise to the main Japanese attack. Later midget submarine actions against Sidney, Madagascar and other places were also a failure, and they were as consequence redeployed as last stance coastal defence. In fact, the first shots and victory in the Pacific War was those of the DD-139 USS Ward (here represented by USS Kane) against one of the Japanese mini-submarines, sinking she. This scenario is an essay to force the limits of the GE and the DB, and of probably impossible victory for the Red/Japanese player (Some hints: one solution can be to slown down the game to 10 or 30 seconds compression and reset the height to periscope deep each time the submarine surfaces, it's possible to penetrate the port and get again periscope depth in the interior bay). As Hawaii is not present in the WestPac map, I used the wider Cavite Bay in representation of Pearl Harbor. Also, I've replaced some few ship classes or configurations with other of similar characteristics. Enrique Mas, August 2012.

File Name: Submarines Galore 1982 !!! File Submitter: broncepulido File Submitted: 05 Sep 2011 File Category: GIUK A submarine-only scenario without other diversions, inspired by some old scenario booklets of the Harpoon 3 series, good for testing submarines (specially the new ones of the HCDB-110831), submarine tactics, sonars, torpedoes and other ASW weapons. Perhaps the Western submarines are numerically over-represented, but it's reflecting the original and very reduced in number of submarines paper scenarios. Also it's configured as a vanilla scenario for lazy players wanting to enjoy a simple pastime, and with the aim of replayability thanks to the aleatority of the starting positions and of the units presence or not presence. I think it's playable at the 10 or even 30 minutes time compression ... before any contact. Scenario Background: The South Atlantic War is going very bad for the British side from a few weeks ago and the South American countries are openly supporting Argentine, menacing with the employ of military force and with the blockade of the British sea lanes southwards. As consequence most of the Royal Navy operational SSN are concentrated keeping at bay in port the other South American navies and preventing his intervention in the Argentine side. This movement has provoked the hard-line communists in the Kremlin to start a submarine feint againts the NATO forces in the GIUK gap, perceiving a good oportunity for start a war with any little casus belli as excuse and defeat the Western Alliance with the Royal Navy engaged in the South Atlantic, At the start of this covert WWIII in the North Atlantic on 1982, the bad weather and also the political uncertitude precludes the use of air and surface assets. To keep low the social unrest because the war, the opening naval actions are limitated to the discrete submarine operations, in a situation remembrance of the 1939 Phony War and of the 1994 Tom Clancy's novel Debt of Honor (where both Japan and the United States are in war against the other, but both governments are occulting the fact to his respective public opinions to prevent the collapse of the stock markets), but these underwater actions are not less decisive or murderous than on a full open war. Enrique Mas, September 2011 Note: September 2011 editions were only for best setting of submarines speeds and depths. Modification 23 December 2011: older variants of previous submarine classes replacing erroneous period variants (As Agosta (1980) replacing Agosta (1988)). Old variants of British SSN replacing some Oberon class SS. New submarine class replacing erroneous types (As Narval SS replacing Daphne SS). Click here to download this file

File Name: "Iron Lady" SNS Dedalo, Mediterranean ASW 1989 File Submitter: broncepulido File Submitted: 17 Apr 2011 File Category: MEDC A Mediterranean basically ASW scenario inspired by the old scenario booklets of the Harpoon 3 series of the late 1980s and early 1990s, good for easy gameplay and for testing generic tactics and weapons. Actually is a mix-up of individual naval scenarios as only the Computer Harpoon can provide. And reflecting all the knowledge adquired the last years in some matters, as about Soviet/Russian platforms and forces composition. The scenario is also a tribute to the USS Cabot CVL-28/SNS Dedalo R01 and her American and Spanish crews. Dedalo/Cabot was a Leyte Gulf veteran, survivor of two Kamikaze impacts and many more suicide attacks, and called by Admiral Halsey "Iron Lady". Serving in the Spanish Armada from 1967 as helicopter carrier and equipped with Harriers from 1972, historically Dedalo was decommisioned contemporary to the scenario timeline, traversed the Atlantic Ocean the last time from 12 July 1989 towards New Orleans and was sadly scrapped on 2002 after some failed attempts to preserve she as museum ship. The scenario reflects the start of the conventional WWIII as was forecasted for about 1989, the first movements in the Mediterranean Sea to determinate the early control of the sea lanes, and the first days of open combat after the previous period of Phoney War. Modification 18 April 2011: missing ASW patrols in the Dedalo group added. Modification 9 May 2011: 1xalternative starting point changed for Agosta, to prevent running aground.

Modification 19 May 2014: some older variants of previous submarine classes now in the DataBase replacing erroneous period variants.Modified presence probability of some subs because previous confussion about percentile addition, the probabilities are now more evently distributed between the submarines, but the probability of presence of a diesel-electric boat is now half of the probability of a nuclear boat. SSBN presence probability increased. Enrique Mas, April 2011 Click here to download this file
