Page 2 of the H4.1 Data Annex is titled A Guide to Trilogy Ship Listings. "ESM/AIR: Surface ships use only the first field while subs use the second. No surface ships carry an ancoustic interecept receiver. The generations are listed as 1st/2nd/3rd Gen. For subs, the two ratings are separated by a slash." In working up an Improved Los Angeles Class SSN, its ESM/AIR rating is 3rd/4th Gen. How are the 3rd and 4th Gen ratings utilized? I'm assuming 3rd Gen ESM would be while on the surface - a la a surface ship? I'm drawing a blank on the "AIR" rating. Thanks

Hi guys this is officially my first post. I start the proceedings with two questions that might have already been asked. So just bear with me for a moment . I've read the posts on H4 paper rules and I found them extremely interesting and informative. So much so that H4 is on its way to me from the US, (no dealers locally). I have been the proud owner of H3 by GDW for a few years and I also own H3 ANW for PC but it just does not have the same enjoymement level that I experience with the paper rules. So, having expelled much hot air here is my questions: I have read about a plotting board used for gaming (I think solitaire games). Where is it possible to obta…

My initial idea was to see the effect of various different units carrying out an attack against an airfield. In my mind I viewed the airfield as an isolated not-well equipped one somewhere in Africa (think the book/movie “Wild Geese”). Then I decided that the airfield consisted of a few different things, and I planned to have each of my attack craft deal with different layers of the airfield. So I rolled what I wanted to do up into a single planned attack against the same airfield in this AAR. I’ve drawn up a map of an airfield on graph paper. Each square is 50 yards. There is a runway 2km long, single radar (single square) control tower (single square), 2 x …

Once a submarine passively detects a contact and develops a TMA solution, what sort of information is obtained? If a "Good" Solution is obtained, does the submarine know course, speed and range to the target? What about "Fair" and "Poor" solutions? This becomes important when firing torpedoes with limited range and enable points ect. Thanks

Here are the Windows and OS X versions of SimPlot 2. This is just an alpha test, but since I have no in-house staff, I am going to use you guys as the alpha testers. This version only supports single player operations at this time. I will have multiplayer up and running for the beta test. At this point I just want some feedback on the look and feel of the display and supporting windows. I am especially interested to know if the separate land and border maps are useful. Honestly, it would be easier to just have one map with land and border, but I have seen some Navy displays that only had borders. Please be aware that some things are easy to break, as error-c…

Would use of an active jamming pod preclude the use of an anti-radiation missile from the same or co-located aircraft?

While it does not appear in Annex B, here is what I have gleened from the manufacturer and fas.org. They give roughly the same info: Size/Signature: VSmall (my idea) Sensor: CCD (Day only) or FLIR (Day/Night) (would need to assign a generation) Ceiling: 15,000 feet Speed: 65kts Cruise, 110kts "dash" Range:100km Fuel: 11 USG Would you like to add anything to that?

I am stepping through an engagement between an AH-1W vs a ZSU-23-4. The AH-1W, with a 2nd Generation APR-39A(V)1 RWR and AGM-122A SIDEARM at low altitude can detect the radiating ZSU-23-4's Gun Dish Radar at 69nm (ZSU is on terrain <100 feet high)and engage it with the SIDEARM after conducting a pop-up to Medium Altitude undetected between 4nm (Gun dish detection of a Small Target) and 6nm (max range of the AGM-122A). The SIDEARM inflicts 1DP. How would this attack be resolved? 6.3.4.2 Guided Weapons appears to be where I should find the instructions, but it only addresses Command Guided and Semi Active Radar (SARH) Weapons, Semiactive Laser Homing (SALH) Wea…

This is a post on HCE regarding the FREMM ASM towed sonar Captas and Sonar 2087... "I was lacking H4.1 data on both these sonars when they were created in the HCDB. If anyone has H4.1 data or suggested provisional data, I'd be glad to receive it." Does anyone have info on these? Thanks.

4.4.2.3 Towed Array: "All towed arrays are either classified as Low Speed or High Speed arrays. This is the speed it can be towed without reducing its detection range because of flow noise." Is low or high speed defined anywhere - I'm guestimating that it is the 0-50% and 51-100% of the platforms speed per their data sheet?

Tensions between the United Kingdom and France have crept close to breaking point (again?). The French destroyer Aconit has entered waters it has been told to keep out of. The UKs response is to send 2 Sea Harriers to ward her off. The two Sea Harriers approach at 450kts and very low altitude. Initial range is 16.0nm. The Sea Harriers pick up the Destroyer and continue to close. The Destroyer detects the 2 aircraft at a range of 13.5nm. At 9.5nm the Aconit begins trying to shoot down the incoming Sea Harriers with 100mm guns but is unsuccessful. The Sea Harriers continue to pass their low altitude die rolls (not crash) and fire their Paveways when at a range of…

File Name: SimPlot File Submitter: kmart494 File Submitted: 13 Nov 2015 File Category: Application/Tools/Mods/Docs SimPlot (simple plotter) provides Harpoon4 players with the ability to add, delete, modify, and move Harpoon units using a graphical environment. Even a background map can be used to increase scenario realism (although a map is not required). See the SimPlot Readme pdf file for instructions on how to use the program. A copy of The Admiralty Trilogy Harpoon4 paper rules are required to use SimPlot to its fullest potential. The program is available for Windows only, and has been tested on Vista and Win7.

File Name: SimPlot Viewer (beta) File Submitter: kmart494 File Submitted: 16 Jun 2016 File Category: Application/Tools/Mods/Docs SimPlot Viewer (beta) is a SimPlot application for multiplayer Harpoon games. When a referee sends SimPlot turn files to players, the Viewer will allow them to create their own unit range circles, reference points, and plot the suspected location and type of enemy units (independent of the referee and other players). A new feature that I am testing is selectable icon size. Four sizes are available: 8x8 (dots), 16x16 (reduced), 24x24 (default), and 32x32 (enlarged). This is very similar to NTDS standards for icons. The "dots" s…

There is a new update subpage on the Clash of Arms site. Here is info on the long awaited Harpoon Naval Review 08. HNR08 Update 96 pages BABY.

Does the APG-70's SAR/ISAR characteristics allow for target classification the moment of it's detection? If so, this appears to give such an aircraft quite a bit of standoff in relation to its other detection assets such as LANTIRN and FLIR. Based on a detection/classification by SAR/ISAR, I'd assume that the aircraft would then attempt to best position itself to effectively employ its weapons within those weapon's particular envelopes and other guidance parameters. Would the APG-70 hand over such target information to the LANTIRN Pod so that the pod would be cued to those targets. Thanks

1) A Mirage 2000 and F-15 are approaching one another. The Mirage is armed with Magic AtA missile which has a range of 6.0nm while the F-15 is armed with a Sidewinder with a range of 9.6nm. Does this mean the F-15 gets to fire its AtA missile first since it will be in range first (using engagement turns)? And depending on the missile and planes speeds, the sidewinder may shoot down the Mirage before it gets within range to fire its Magic (within 6.0nm)? (Maybe i have answered my own question, rule 6.3.3.2.1 says in the engagment turn a missile reaches a plane the plane must evade and therefore cant fire). If the sidewinder does not reach the mirage before t…

In coordination with my own testing of the New Trilogy Air Rules, I went beyond simple dogfights and cobbled together a old soviet-style attack on a battle group. In this case a squadron of 12x MiG-29 (4x R-77, 2x R-73) is attempting to sweep away opposition for a squadron of 12x Su-34, in the ASuW role. I made a number of assumptions: that the carrier's E-2C (high altitude) APS-138 would detect the "small" incoming MiG's (high altitude) @ 130nm. that at least 4x F/A-18C would be vectored in to intercept. that with the guidance of the E-2C, the F/A-18C's would get the "long range drop" on the MiG's with 1x AIM-120 per F/A-18C being launched first, at rela…

Harpoon II arrived today spectacularly packed. I almost felt bad removing it from the acetate envelopes complete with stiff cardstock to keep things from bending. But was I ever glad I broke the seal! Harpoon II looks a lot like Harpoon 3 except I like the organization of Harpoon II better and its greater number of diagrams really impress me. There is a diagram showing a multi-game-turn ship turn instead of having to guess and divine if I move first, turn first, jump around three times,... As for the organization, the rules are categorized by their order in the turn whch I find very helpful. Perhaps more comments once I really have a good read of the ru…

Hi guys, my harpoon paper days are starting again, as illustrated by my purchasing saga. Going out to buy the 2003 review just after posting this. Last time I played was with H1 or H2 rules, back in the mid-80s, only played computer variants since then. No ground back then. So I've heard and read about ground rules existing for H4(.1), but not being up to date on what is what and where it is (much less its cost, hahaha), I'm asking for your help, dear pooners. Interested in "official" ground combat rules, be it in commercial or free, paper or online, supplements, as well as community mods, hopefully freely available. Or barring tailor made systems for H4.1, g…
