Scenario Design & Discussion

Two Mirages’ are tasked with engaging a Perry class frigate. In the war room based not far from the coast, the two Mirage pilots go over their plan to attack their Perry class target. Each Mirage has an option to carry one of two weapons, and the pilots have decided to carry one of each in a co-ordinated attack. Piper 1 will carry an AS-37 missile, which is an anti radiation missile that will home in on the Perrys radar while she has it active. Under this blanket of radar darkness, Piper 2 will launch its AS-30 from a range of 5 miles. The pilots consider the most likely case that the Perry turns her radar off and is unable to direct air defences against …

You are the Commander, Training Squadron of Blue Force. TS departed the last port of the ocean training cruise, and go to home port. But, Blue and Red nation skirmished accidentally in the Alfa islands yesterday. The prospective course of TS is now in a tense atmosphere, so the joint staff office detached one P-3C MPA to your force. 2350 in local time. P-3C contacted a very small surface target in the front of your force. It's like a submarine's snorkel. Here is the choke point, so that contact must be identify and observed. But P-3C had to depart here in 20 minutes because of fuel. You command your ships, a helicopter, and MPA, keep contact and identify it.…

I sort of fell into this beginning saturday and finished up tonight. Don't put too much credance into this yet as it did not start out too "detailed" in planning. The twist was that I was interested in a possible airstrike on an Iranian weapons lab/complex. I used a modified Appendix 5 Gaming the Kola Air Defenses from High Tide. By modified, I ignored the Off-shore AEW/Interceptor phase as I assumed that a pre-mission fighter sweep would have taken its toll. The second and third modifications were SWAG's to the GCI Fighter Table and "Iranian" Fighter Type Table. I did not believe that the Iranians could get anything above a squadron in the air and within range o…

I thought I'd post this AAR up of a game I was playing the other night. In this scenario, the Russians have occupied Bardufoss airbase in northern Norway. The Norwegians are at Bodo airbase in the south and are attempting to defend it from attack. The Russian OOB consistes of 20 SU-27B Flankers and 20 SU-34 Fullbacks. The Norwegians are equipped with 20 Eurofighter Typhoons. The scenario began at 0200 local time. The Norwegians launched a CAP of 4 Typhoons 100 nm north of Bodo over Norway. At the same time the Russians launch a probe of 4 Flankers to see if there is any opposition along their proposed strike flight path which will taje the strike force out to …

The SSN USS Virginia's mission is to infiltrate a Norwegian fjord to disembark SEALS. As the sub was enroute sonar detected three ships eventually identified as a Udaloy, Krivak 4, and Sovremennyy all between 7 and 10 nm away. The best russian passive sonar range was about 2nm while the sub had a towed array sonar with a range of 10nm. The sub launched its torps at 5 nm from the Udaloy and about 7 miles from the Sovremennyy with the Krivak in between. The Mk48 Mod 6 travelling at 65 knots easily chased down and destroyed the Krivak and Udaloy.With the tubes and wires cleared and reloaded I fired on the Sovremennyy but it was too late. After seeing its two compani…

Pirates of the Caribbean Military juntas have taken control in Cuba, Haiti, and Venezuela. These juntas, closely allied with each other, are ruling their countries with an iron fist. In addition, they have given safe haven to pirates and dealers in the drug trade for a portion of the proceeds. Representatives of organized terrorist groups have also been spotted in the area. Scenario 1—Lighting the match Lookouts on the new US Coast Guard Maritime Security Cutter have sighted a trawler full of refugees from Cuba. The Cutter initiates a radio call to the vessel. Meanwhile the trawler is being pursued by a Cuban Osa class missile boat. The Osa has the trawl…

Situation Libya. Present day. A French Jaguar has been tasked with destroying a bridge. In game terms, the bridge is a medium sized target with 100dp. The Jaguar is armed with 5 x EU3 450kg free fall bombs and has a ballistic bombsite. Each 450kg bomb inflicts 41points of damage. A single hit could potentially make the bridge unusable, 2 hits would almost guarantee making the bridge unusable and had a good chance of destroying it. 3+ hits would destroy the bridge. Pre-flight planning A horizontal bomb run is safer than a dive bomb attack. However during the pre-flight planning phase it was discovered that a horizontal bomb run yielded just a 6% chance of h…

That said, does anyone feel that it may be wrong that two AM.39 Exocet Block II missiles remained undetected until immediately before impact on a tanker and an LCS. The LCS had active TRS-3D-16 AS radar. The missiles were launched from 25nm. The missiles have a cruise profile with and are sea skimmers so they would be at very low altitude. I am trying to balance my concern that I may have calculated the engagement wrong versus underappreciating the capabilities of the AM.39 Block2 3rd Gen SS, TM missile. Thanks

The following is a small scenario inspired by the Second War of the Pacific article in Harpoon Naval Review 2000. This was just to test using SimPlot to map out a paper rules game. The scenario takes place during a hypothetical war between Peru and Chile in 1995. Peru has sent a frigate to patrol off the coast of northern Chile, since their intel says all the fighters and ships at the Iquique Airbase and Naval Base are deployed elsewhere. The ex-British Daring class ship Palacios will operate alone due to a lack of opposition. However, the Chilean Air Force has one F-5E left at the base due to maintenance problems. The airbase has picked up an ESM contact that…

Based on various sources and discussion on the HG chat this evening, the following data has been "agreed" upon as workable. max speed: 18kts range: <60nm size: Vsmall signature: quiet capacity: 8-10 pax 1 DP 25% max speed at Sea State 4+ Comments appreciated. Pete

Has anyone got any engagements or home made scenarios, possibly with some special rules or starting conditions, using a small number of units?

Depth Shallow 125 Battery Units 1st Hour @ 16kts = -15 units 110 Battery Units 2nd Hour @ 16kts = -15 units 95 Battery Units Go to periscope depth IOT snort, decrease speed to 11kts 3rd Hour @ 11kts = -4 Units 91 Battery Units, but charging equals +10 101 Battery Units Descend back to Shallow. 4th Hour @ 11kts = -4 Units 97 Battery Units remaining 30min @ 11kts Contact, bearing 336 degrees.

In layman's terms what would be the sequence of action for a MH-60B dropping sonar buoys in search of an anticipated, not necessarily suspected diesel electric sub. I'm solo'ing part of that HNR03 LCS scenario again. Right now, the convoy is reaching a choke point and Red diesel electic boat is missing from the port it was last seen. An MH-60B has been punched out. Scale at the moment is 1"=1nm. I have set up a 10x10 square inch box (using 1" square graph paper, with 10 sub-divisions per "box"). I roll a D10 to come up with which box the DE boat is in, then roll 2D10 to come up with a four digit grid coordinate for its exact location. I then do the same for the …

Thanks to Brad for listening and commenting on my walk through of a night helo insert into what I now realize is a high anti-air threat environment and now must come up with a new way to insert my "eyes" onto the island. As it turned out unless I can use intervening terrain against the Straight Flush radar of the SA-6b battery, I risk being shot down by a tied-in SA-9b at a pH of 50%, even while flying VLow/NOE. The trick is locating the radar set, especially if it moves frequently. Small Boat insert may be the next option...

Hi all I am Silver_Dragon, a Dual Lurker for the phase two in the Global Thunder operation and the lost persial gulf, sparky island MBX. I live in spain, and Me and the spanish comunity has very pleased for the megascale operation. My intencion is make a limited operation similar at GT, with a Strategy Phase Web site, Operational Harpoon 4.1 Phase and and Computer simulator Air / Naval / Sea Tactical Phase. Mi idea is make a Scenary in the Magrev - West Mediterranean zone Blueforce Spain, Portugal, Morroco Redforce Argelia, Tunicia, Mauretania, Libia Phase I Strategy: 6 months - 1 year of game time, 3 Vs 3 leaders Phase II Operational 8 hours p…

How do you do? I'm glad to join this community ,and meet the players of Harpoon4. I'm from Japan, and Japanese Defense Navy will commission the new class Destroyer, we call 25DD(25 means Japanese financial year based on emperor). She will have Multistatic sonar capability, but Harpoon4.1 is not covered this new ASW technology. What do you think about how to evaluate that?

I am playing the Indian Ocean Escort scenario from HNR'03 using SimPlot. I am going to use many screenshots to help illustrate how SimPlot can be used to play H4. I apologize in advance if this topic eventually takes too long to load. I will limit my posts and screenies to just relevant points in the game. I will make one post per relevant turn. Below is the starting position of all units (0600). Because this area is heavy with civilian air and sea traffic, there will be additional neutral units that come and go within the game screen (which is between South Africa and Madagascar). Civilian ships will use Nav Points R007 and R008 as shipping lane turning po…

Ran through the Intro to H4.1 AAW last night. US wiped up the floor with the Russians 4:0. Each of 4x F/A-18C launched 1x AIM-120's at 40nm. A second salvo of 4x AIM-120 was launched at 33nm before the 4x Russian MiG-29A could respond with their long range threat, R-27R, letting loose with 4x AA-10 Alamo's. AIM-120 4th Gen 7.0 ATA vs MiG-29A 5.0 ATA +1 for 2nd Gen J&D. 7-6=1.0 or =<40%. This is when the dice gods stepped in and the US rolls 16, 19, 84, 19 - three hits. Feeling bad for the opponent, I roll for the 4x Alamo's before the rightful second wave of AIM-120's. R-27R 3rd Gen 5.5 ATA vs F/A-18C 4.5 ATA and 3rd Gen J&D. 5.5-6.5= -1.0 o…

I'm loving the Harpoon V rules but find that I need to enter them slowly in order to get the hang of one portion of the rules before entering into another set (figure out SSM and SAMs before venturing to aircraft, subs, etc). To learn the basics I set up a very simple scenario that has great replayability and has been good fun each time I've played it. Scenario set up - March 22, 1988, 0600 local, 200nm SW of Tromso, Norway. Sunrise 0304, sunset 2230. Sea state 4, wind from 000, no clouds, visibility 60%. The Soviets have invaded West Germany and war is on. Unfortunately the start of hostilities found numerous merchant ships, NATO and Soviet at sea. The Norwegi…

I created a modern RAN vs. PLAN scenario using online tools, designed for solo play as the Royal Australian Navy. It can easily be adapted for co-op or competitive multiplayer. This is my first attempt, so feedback is welcome! ChatGPT acts as an intelligent, responsive opponent—managing PLAN movements, sensor results, and combat outcomes without the need for tables or extra players. It understands Harpoon mechanics and modern military doctrine, resolving detection, weapon effects, and electronic warfare while preserving fog of war and narrative tension. It also generates mission briefings, radio chatter, and tactical commentary to enhance immersion. No setup or softw…
