Status: offline 		This is my first scenario for CMANO. The Carl Vinson and Kitty Hawk CVBGs are moving in on Kamchatka to strike the submarine facilities at Petropavlovsk. I selected the year 1985 to have more emphasis on fleet air defence, ASW and strike operations and less on fighter air combat. The scenario is quite long and slow paced at some points, but I wanted to give the player enough room and time to approach the target in a deliberate manner.

Comments and suggestions are greatly appreciated. If this is received well, I might expand this to a small series of scenarios.

Some questions regarding scenario editing:
-The default file name for user-saves for this scenario is the name under which I saved the scenario for the first time (which was just a working title). Is there a way to change this default to the current scenario file name?

-I wanted a message to pop up when an area has been cleared of all enemy submarines (whose amount is variable). Since I did not find a trigger like "unit NOT in area" I set it up as follows: A dummy side is used as a variable and points for this side as value. A repeating trigger adds +1 to the variable as long as there are subs in the area. A second repeating trigger continuously subtracts 1 from the variable. As long as there are subs, the variable remains at 0. Once all subs are destroyed, the variable drops below 0 and a message is triggered. Now, is the performance hit of having two triggers firing every second something I should worry about? And is there a simpler way to achieve the same goal?

Status: offline 		For the last part: is it completely about destroying all the subs, or is it also an option that the enemy subs leave the area without being destroyed? If the former and they all need to be destroyed then maybe a simpler way is to add 1 point to a non player side every time when a sub is destroyed and when the score reaches the amount of subs, trigger the message. Make sense?

Status: offline 		It is also about subs leaving the area. So the trigger has to detect "no more subs in area" rather than "x subs destroyed".

id like to see this a little richer.. couple of more layers of events...
ok.... id like Shemya to be under my control.... i think there should be more purpose and assets at shemya... its just kind of there as some token now..... maybe have the commies try to strike it or something...

some supply ships with the cvbg or a supply group trailing might be cool... that has to defend itself...

Yes, as mentioned above this was the only way I could make a "no unit in area" event make to work. One of the scenario objectives is to sink all subs anchored in the harbour. A trigger constantly checks whether there are still subs in the harbour and adds to the counter. Another trigger constantly subtracts from the counter. As long as the objective is incomplete, the counter remains in balance. Once all subs in the harbour are sunk, the counter starts to drop below zero and a third event triggers the completion of the objective.


Another question, is there a way to have a trigger on laying mines? One of the scenario objectives is to mine the harbour enterance, but so far I have exluded this from determining scenario victory.

Status: offline 		Hi, I played the scenario until I destroyed all subs and its a good scenario with plenty of potential but am I missing something or has the trigger for the Backfire strike not been put in?

I intercepted all Bears before they could spot my TF on radar and thought, this is lame so I let the last Bear close on my TF and activated all bells and whistles in my TF and nothing happened. I checked the editor and could not detect a trigger so I guess that this still is a work in progress?

Also, the USSR's air opposition is a bit laughable, in two fighter sweeps my Tomcats destroyed all enemy AC without them even getting of a single shot of. Also, using two carriers for this mission is overkill, with some planning you can easily destroy all the air defense sites around the harbor and the subs/ships in it with a single strike.

Thank you for your feedback. The Backfires are not triggered but set up with an open strike mission, so they should launch as soon as your ships are detected. I agree though that Soviet recon is quite limited. The patrol aircraft are easily held at distance and sonar performance of Soviet submarines is laughable. If I let the mission run withouth launching Tomcats, the Backfires do destroy at least a carrier. I would love to make the threat of a Backfire strike bigger, any ideas how to make Soviet recon more potent?

Regarding the Soviet fighter defence, a Su-15 regiment was all that was historically based on Kamchatka in that period, so I wanted to keep this. Regarding the two carriers, I belief that such high threat areas (also Norwegian Sea or Eastern Med) would not have been entered without at least two CVBG. One carrier alone is actually not able to continously put enough Tomcats in the air to defeat a divisional Backfire strike.

Status: offline 		If I can give you some advice, have a look how Yokes build his Kamchatka scenario (Kitty Comes To Kamchatka ). His scenario is basically the same sort of scenario as you have set up but with just a single carrier and a much stronger air opposition (although his Backfire strike is preplanned, it's NASTY). Have a look and if necessary modify some of his ideas and credit him in the scenario description accordingly. Alternatively, use satellites to detect the US fleet and trigger the Backfire strike. Also make the random deployment area of your subs smaller, I now only found and destroyed a single one (also found 5 biologics) as the rest of the subs turned out to be deployed to the west of my route and strike point. As players will have to wait until they are at least within 400-500 miles from Kamchatka until they can perform a meaningful strike and mostly tend to not vary their course to much in order to get there ASAP, you can exploit this by preplacing subs in their route (I would not worry to much about replay value, this scenario is to small for this. just offer players a solid single or two play scenario with preplaced subs instead ).

Also let your submarines use kinematic range launches against targets, this lets them at least get a shot of before they come to close to the TF and are almost certainly detected and destroyed by the US ASW screen before getting a shot of.

Good luck!!

When I was playing, it at least looked like the Backfires came near the range to shoot at me, but turned bingo fuel just before the range. I'm not sure if it is possible, but maybe you can set the mission so that they do not takeoff before I'm close.

I do not think range is a problem, I just had a very successful Backfire strike almost at scenario start. I belief this might be related to the target contacts getting dropped after too much time, at which point the Backfires returned to base due to lack of target (I have seen it once too). I hope I can resolve this by giving the Soviets a more robust recon.

Status: offline 		What Willie says is pretty right..... I would like to see it a little more evolved some more layers of events… Would make it more demanding an immersive… Like there could be in here screen around Russian facilities… And some logistics going on or something like that... would be cool and more assets at Shemya...
I'm only a few hours into it and playing it right now actually… I like the basic premise of scenario a lot… Good luck…

Status: offline 		I concur with magi that some screen around Russian base would be nice. So far, I figured I can sort of cheat by driving subs at flank speed inside the base and shoot there. I cannot get subs, because the shore and geometry does not permit a torpedo shot, but I can get ships and this weakens Russian SAM capability at least somewhat. TO a full blown cheat, Baloogan-style, I fired a nuclear SUBROC at the subs :) That did some good damage. From the Russian perspective, I would certainly have approaches to the base and probably the narrow part of the waterway mined, just for the case of rouge sub driving in.

Status: offline 		Thanks again for all the feedback and suggestions. I made some adjustments and updated the scenario in the first post.

-I found a mistake by me that actually prevented all subs from opening fire. I was under the impression that units would assume the ROE of a mission when it was activated. It turns out they do not (I thought I could have a different ROE for units before they go on activated missions). So now all subs should attack correctly.
-Then I made the Soviet submarine screen stronger and set up more deliberately instead of just having a large random patrol area. The most capable subs of the Pacific Fleet (Victor IIIs and one Akula) are now forming a barrier which should greatly increase chances of even making contact with the Task Force. This in turn should solve targeting problems for the Backfires as well as provide targeting for SSGN in position behind. Otherwise Echo II and Charlie I will pretty much never find a target on their own (a flanking carrier needs to approach to 4 NM to be detected by their sonar).
-US SSN removed, as I do not think they add much to the overall scenario (and would probably have been sweeping the area way earlier anyway than the scope of this scenario).
-Concentrated biologics more closer to the player's task force.


I consciously left out meaningful Soviet coastal and ASW defenses of the base (other than some ships for scenery) as well as P-3s from the Aleutians, as I became concerned about performance if they start to drop hundreds of sonobuoys. The scenario is quite long and requires a lot of time acceleration which already now hardly goes above 15x (quickly testing anything beyond a couple hours after mission start became next to impossible). I think adding even more stuff will kill it. I removed the US subs, so the lack of Soviet ASW doesn't matter that mach (let's just assume both is happening behind stage).

Regarding the overall composition and strength of the enemy (fighters, air defence, subs) I would like to keep it like that. The scenario represents to the best of my knowledge the assets available in the area in May 1985. I wanted to make this scenario also to study this real-world setup for my own curiosity. So if it turns out a USN carrier attack on Petropavlovsk would have been a walk in the park in 1985, then my scenario will also be easy :) The concentration of subs in front of the task force might already streching it as far as bias for the Soviets goes.

I had a Backfire strike on me. Actually surprised me pretty badly - I'd never been on the receiving end of a large-scale off-axis missile strike before. I didn't take any losses, but it was very, very close going. Took me a while to understand what I was seeing because the jammers were so effective.

Status: offline 		Wow, your new version is MUCH better than the old one. I just actually lost a ship to a torpedo despite taking full ASW measures!! (I think this was only the second time that this has happened to me) :)

Well done on the subs, now to find out how the rest of this mission goes :)

Status: offline 		Ok, I finished the scenario again and your Sub deployment is excellent in this version but I still was able to avoid the Backfire strike by intercepting the USSR recon before they could get a radar picture of my TF's and by staying EMCOM silent. Only by letting a recon plane get close deliberately and turning on all EMCON bells and whistles I was able to trigger the strike. I still advise hard-coding a Backfire strike as any decent player will simply go EMCON silent at the beginning of the scenario and use his bountiful support assets to get 24/7 radar AND fighter coverage and will thus easily avoid the strike..

Status: offline 		I am glad the subs are working better now but your Backfires seem cursed. Since you were attacked by submarines, your ships must have been detected. I wonder why this didn't trigger the strike. I tested this twice yesterday by completely removing the patrol aircraft and each time the subs provided targets for the Backfires.

I guess it is not realy worth the hassel and the Backfires are better scripted than dynamic.

Status: offline 		soviet doctrine relied on reconnaissance .... You should have more Reconnaissance aircraft… with some defender for them…you could have foreign flagships friendly to read side as tattletales .....
I think having a US sub or two it's more realistic in this type of situation… I believe your cvbg groups normally would have more helicopter asw assets .... I don't tend to be a creative cheater myself… And I really like scenarios that are more plausible… But this thingh is fun and I'm going to download your later now and check it out…
I still think it would be nice to have more assets at Shemya as it would be realistic… I know I'm a terrible guy because what I'm talking about his scenario Creep....I guess you guys call it…. All the cool stuff makes it more interesting for me…

I am going to load this one and start over…… Cool...

Status: offline 		The question of how the Soviets envisioned to find targets with aircraft actually leaves me puzzeled. Playing it out in CMNAO suggests that it would have been very easy to destroy recon aircraft before they are within range of a CVBG to detect it with radar. Sure, the presence of radiating E-2 Hawkeye would give away the presence of a carrier in the AO. But it seems very unlikely that a carrier could have been located from recon planes with enough precision for an airstrike. In addition these were actually quite sparse assets (in the Pacific Fleet just one Tu-95RT regiment and one Tu-16R squadron, plus a regiment of Tu-142 and Il-38 ASW aircraft each), with no fighter capable to provide escort available in 1985. The only option I could think of is to support Tu-95RT with Tu-16 jammers, but I have never read that this was practiced by the Soviets.

That is what I like about CMNAO so much. It helps to visualize and put into perspective a lot of the stuff I just know from the books.


Regardning the US SSN, placing them at a realistic distance in front of the carrier at scenario start would actually put them beyond the bulk of Soviet subs (with the Soviet subs between the SSN and the carriers). This would be hard to justify. In order to have a SSN sweep through the Soviet subs, the scenario would have to start 24h earlier with the CVBG still a great distance further away. But I guess this would actually be better explored in a seperate scenario.

On a seperate note, anyone has a particular comment on performance? I cannot reasonably go above 15x time acceleration (it probably doesn't even reach this), so I was very cautious with adding more stuff (which I would love to do). Is the scenario faster for others or simmilar?

Thanks again for all the feedback. I will soon do another small rework of the scenario.

Status: offline 		I also replayed the latest version of the scenario without any issues. With some modification to my ASW screen I was able to get into strike range without being detected (sinking five subs while doing so) and thus avoided the backfire strike once again :)
