Probably of great interest, history of the SQS-26 sonar by one of its designers. Thanks Bob Mack. https://apps.dtic.mil/sti/pdfs/ADA538018.pdf

51 years ago, twelve F-4s, from the 8th TFW, released Paveway “smart” bombs, to finally knock down the Thanh Hóa (Dragon's Jaw) Bridge in N.Vietnam (April 27, 1972). Previously, 871 conventional bombing sorties had only succeeded in scratching the bridge. Air Power

When testing with Don's Scenario I have found that the actions of the land missiles seem to depend on the quality of the sensor detection and the condition of the original target. When firing missile from to units at the target but only one target per unit both destroyed the target and no hits on ships occurred. When both attacking units targeted both AD units the first missiles to get there destroyed both targets. When the second unit reach target location it seems to change that location to a BOL activation destination and those missiles would fly on and lock onto the ships and attack them instead. As TonyE said they were quite the little overachievers. In one case the first missile set failed to hit assigned target but the second did kill it. No ships were targeted even though the missile flew by the ships. I also notice that if the lock was not solid the missiles would reach the target area and revert to what seems a BOL activation point and kill ships instead.

Remember to take the built-in WestPac scenario for a spin too.

Fix confirmed for affected scenarios.

HCE - 2023.004 - 2023-04-04 =========================== - Chg:32897 GE Rather than loosing attacks against submarines from close to a weapon's max range, now prompt to fire them from at most 2nm away. This could negatively affect weapons like CAPTOR mines that might ideally loose their torpedoes from farther away. It would be a good thing to test. https://harpgamer.com/harpforum/topic/32897-stand-off-asw-weapons-failure/ (thanks Enrique)

An account of the sinking of Moskva that claims radar ducting: It became known how exactly Russian cruiser Moskva was discovered and sunk: details and photos (Ukrainska Pravda)

I'm guessing us mortals are of no help?

I am a librarian at heart and what I can't find on the internet or fragmented I like to gather all the information, cross-check it and make a synthesis. in absolute terms, I have given myself the task of doing the same for the navies of the world, for aviation and land military equipment. My default is to be a perfectionist and therefore I constantly modify what I do before expanding. As long as I'm not satisfied with what I'm doing, I try to improve. This project is above all encyclopedic and, as a wargame fan, why not integrate this work into Harpoon, CMO and other games. But for that I would have to translate everything into English and return to traditional units of measurement (knots, nautical miles, feet, inches and others...). I preferred to use kms, km/h and other metric units (even for warships) for conversion convenience and speed.

Many night's worth of good reading there. 🥰

New for this version 2.4.2.1 Of Toolbox A new Page KBShortCuts which includes a handy rundown of some of the shortcut keys that give features not obtained through the main F keys. Fixed a bug in the exact fix indicator and 'Cover' function in Attack Tab when player is Red. The toolbox size and position within the harpoon window will be remembered in subsequent games. to remember position follow instructions in settings page. Air Group Formation page gives an indication if the selected air unit is NOE (Nape Of Earth) capable and if its IFR (In Flight Refuel) capable. Air Refuel Page - when you enter this page it now automatically updates the Group list if one of the boxs Active or Tanker is ticked. Recent changes: A revised algorithm for handling attempted captures of enemy and neutral bases and surface groups.

Thanks for your input Enrique. Yes to me this is important. The 'test' version I have operating does this. I think it gives a lot more purpose to having neutral platforms in a scenario. This test version does also include a temporary removal from player control any aircraft that conduct the attack by turning them to neutral until they RTB (generally when they go bingo, but I've not fully tested this), the purpose here is mostly to inconvenience the player in the case they fire upon a non combatant, eg an organic - probably we have all blown up innocent whales. One limitation, at the moment, is that I am 'triggering' from an intentional attack on a neutral platform (this is usually before identifying it's side, so it is yellow on the screen) but perhaps in the future I can extend this to 'accidental' hits where for example a missiles hits a neutral without being aimed at it. If you'd like a 'pre release version' to play with and provide more comment let me know. Don

Fix coded in 2023.010

I'm thinking that if aimed at a land target this type of missile should at least hit the ground somewhere near the target, with its ph probability of hitting it. I don't see they should be cruising off long distances past the target then hitting something. But open to other opinions. If the final hit is within a localised distance from the target, eg a different unit within the targets group (irrespective of sea land), then I'd think that reasonable.

My initial thoughts bearing in mind that we are simulating a wide range of missiles using a very small number of inputs: 1. The player should not be able to launch the land attack missile (LAM) against ships. This seems to be the case. 2. The missiles once launched should be able to hit ships. An inertially only guided weapon would almost never hit a moving ship. An early generation radar guided missile could easily hit a ship. A modern guided missile could be launched with instruction to ignore ships or hit specific ships if they happen to come within seeker range. 3. The missiles once launched should be able to hit any side's units including friendlies. Again, this would depend on the particular guidance method(s), recent missiles could be launched to only attack very specific targets and avoid blue on blue yet most weapons until recently would go ahead and attack friendly units. Please keep discussing what should happen. I appreciate the opening position saying that the missiles should not hit ships.

Image: Mediterranean Sea, Ohio-class guided-missile submarine USS Florida (SSGN-728), equipped with a Special Forces dry deck shelter (DDS) and overflown by a CV-22B Osprey assigned to 7th Special Operations Squadron, 352nd Special Operations Wing (based primarily at RAF Mildenhall), in a special operations forces interoperability exercise, February 26, 2023 (U.S. Navy photo by Mass Communications Specialist 2nd Class Matthew Dickinson/Released/A serviceperson on duty and in consequence on public domain) With the world centred early 2022 on the Russian menaces to Ukraine anything can happen the next months (This was an original phrase of the LCS scenario from where I took part of this text, posted January 30, 2022!) ... but that is now an alternate world. In the nowadays real world, after her April 2006 SSGN conversion, USS Florida SSGN-728 after some months in the Mediterranean Sea sailed to the Persian Gulf, entering it April 2023. Iranian claims surprised the international scene alleging one of its Fateh-class coastal submarines forced USS Florida to surfaced entering the Persian Gulf This apparently simple scenario is developed to test the verisimilitude of those claims. This scenario is simple on its planning and execution, but perhaps difficult to master. I only hope this scenario is not similar to the infamous The Hunt for Red October game (1990).

Notes on some platforms: Against the usually stated 12, other loads of long torpedoes in Ohio-class are: - For Norman Polmar and K.J. Moore in "Cold War Submarines", Potomac Books 2004, page 200: 24 torpedoes. - For H.I. Sutton: 4+18=22 torpedoes. http://www.hisutton.com/World-Submarine-Ranking-Weapons-Load.html - But old reports say many times US submarines sail with only 6-9 torpedoes. - By World Air Forces 2023, later corrected by The Military Balance 2023, the Iranian Navy has some 3xP-3F Orion (at Shiraz), and some 10xASH-3D Sea King, sometimes based at Kish Island (and 3xRH-53D, sometimes based at Bushehr) currently in service, but probably of no use in this scenario because the USS Florida transit should be covered by US fighters. - The Iranian Sea King, introduced 1978, were out of service 1997-2014, and reintroduced 2015: https://www.hispantv.com/noticias/defensa/77289/iran-armada-sayari-helicoptero-sh3-buque

After adjusting ASROC drop distances of torps to target we looked at the distance actually dropped and the torps position immediately after drop. We observed the torpedo was always dropped directly on the sub or 0nm away and also the torps were instantly at the depth of the sub. This was regardless of level of detection or lock on the sub. This gave the sub no warning of a drop on them by ASROC and no time to react or any sensor check might be too long for a detection. I was thinking perhaps a adjustment on flight time might increase the drop distance to the sub a bit and If needed adjustment to torpedoes acquiring depth instantly on drop. Helicopter drops have to start at shallow and make their way down. I have a scenario with a player-controlled sub moving towards a ASROC armed ship at cruise speed and deep. The sub also is active to enhance detection by the ship. The sub will close to 12 nm when ASROC fires at sub. Helicopters are launched by AI on sub too but do not close in time to attack sub prior to ASROC attack. I have attached a test scenario with two saved games one second prior to ASROC launch and two save games prior to torpedo drop. I have also included both message log and GE log collected for the save games. Logs label 2 or for the torpedo drop while the other is for the ASROC launch.ASROC.zip

HCE - 2023.008 - 2023-05-02 =========================== - Chg:33032 GE Split guidance of ANNEX_E (standoff ASW) weapons from the monolithic eff100 to a new eff100E function to make it easier to understand the state machine. Annex E weapons are by definition inertially guided so very simple navigation. This seems to have resulted in far more desirable results. Also set the resultant torpedo to start at Snorkel depth instead of target depth. (thanks TonyD) https://harpgamer.com/harpforum/topic/33032-asroc-behavior/

Don, if you are still having your issue with 2023.002, please post that up as a new issue. I could not and still cannot reproduce Eric's issue when I used just the two listed ExportDLLs.

Yet it works in 2022.027, interesting

View File Malacca Straits A Battleset with inbuilt database and ten storyline scenarios. Installation instructions are in the download zip file. Malacca Straits, Asia equivalent to the Straits of Hormuz. A strategic trade choke points for several Asian countries including China. The straits run along the coastlines of Indonesia and Malaysia with Singapore in the middle. China's major trade route to Africa and the west makes it of high trade and strategic importance. China has for decades claim reef, shoals and uninhabitable island as their territory and by threaten or actual force taken them. The island building campaign first stated as just claiming lost Chinese territories has become a military base initiative to levy control over the South China Sea of which the western part leads to the Malacca Strait. The Malacca straits is located on the western part of the South China Sea which connects it to the Indian Ocean near the Bay of Bengal which is controlled by India. Australia being a large supplier of LNG to India also though not a strategic see value in not allowing China by any means control it. A major part of Chinese energy is dependent on the Malacca Straits and see as a major vulnerability. China through trade agreements has keep the peace with counties belonging to the ASEAN trade pact. The island building program has some countries to back away from China due to militarization of the South China Sea. Australia lately has condemned Chinese action in the South China sea and ever more their interaction with Australian military units. Australians LNG export to India are aided by unmolested transit of the Straits. The U.S. continues its Freedom of Navigation in the SCS but not without harassment and warnings from Chinese built island bases in the SCS. India has maintained as best a relationship with both side with the recent military exercises with China and Russia. While also doing so with the U.S. and E.U. countries. In the region China has used it wealth to create favorable treaties and if needed coercion to control all shipping in the SCS. This leave not only Taiwan separated from possible allies' intervention of a Chinese invasion but many countries in the area also vulnerable. China has laid claim on the Indonesian island chain of Natuna but has yet attempted to move on them. Indonesia is yet an unknown of how far they will go to defended them and who of the ASEAN countries and Australis would aid them in a standoff with China. Natuna island would be a huge advantage for China in not only controlling the western part of the SCS but also that of the Malacca Strait. Malaysia and Singapore are continuously busy with increase pirate activity of whom seem to have an endless supply chain. China has increased it harassment of other countries military forces as they try to surveil the SCS in further intimidation or hiding what they are up to in the Western part of the SCS.

Probably a tip for only the young players (well scenario writers). If you use sea mines it appears that the Misc Settings, AI settings must NOT restrict submarines to remain on their course.

Hi John, Add SAM sites just like any other unit. They are organized in the DB under Intl (international) by origin and with the prefix 'SAM' by name. The entries typically reflect a complete battery (launchers and associated radars) but in some cases you could add higher level radars to the mix. You can emplace the SAM sites individually on the map or add them to formations. I hope this helps.

Database designers generally welcome requests for new platforms, weapons, sensors, etc, especially if you intend to use that platform in a new scenario that you hope to share with other players. Each database has its own design guidelines, so if your request is in keeping with those guidelines, it stands a good chance of inclusion. Database designers are equally appreciative of notes and reminders that a certain entry might contain an error, typographical or otherwise. Keep in mind that any database is always a 'work in progress' and its a huge undertaking to try and maintain one database. Many designers around here maintain several! Also, there may be a legitimate difference of opinion about whether a certain entry is 'accurate' or 'realistic'. While a designer will probably be very happy to hear you out, you should also appreciate that the final decision belongs to the designer, of course, and he may have his own reasons for deciding to take the database in any given direction. There's a dedicated sub-forum for Database Design & Discussion that you will find here.
