Welcome to our new content. As the Weapon Detective, we are investigating modern weapon systems of the Second Cold War. The Weapon Legends is about older weapon systems. In our videos, we tell their epic stories which made them a legend. The Weapon Legends investigates these stories, reads between the lines, analyse, and tells the untold. In our videos, you can find technical information as well as historical backgrounds, what happened during the development processes, combat experience and political projection. Let the wisdom of history show us what the future would be like. Let’s investigate the veteran weapons of the past together.

[@hullutsuhna]

fun fact: in Finnish service the OSA-II "Tuima-class" was informally known as "Tuska-luokka" ("Agony-class") & sometimes as "Moskvitš-class"

[@fanaticduck5125]

How do you not have more people watching and subscribing? This is so good.

[@kkang2828]

It was a gunnery-focused ship built at a time when ASMs were fast becoming the main armament for naval engagements.

[@matsv201]

ASM wasn´t really becoming that potent untill the 70s. Really after the prime of this ship

[@Satunnaistasotilashistoriaa]

Nice video! I think You nailed very well the unusual characteristic of Turunmaa -class!

[@WeaponDetective]

Thanks again for sharing your unique video footage and information with us

[@habahan4257]

Amazing video. Please keep sharing videos about little-known systems like this. Well done Finland

[@WeaponDetective]

Thanks for your nice comment. We will keep making

[@roderickcampbell2105]

Hello Haba. I agree completely. And thank you WD! Great report.

[@mystical7392]

Great content. Could you do a report on the Swedish built patrol boats that were built for the Trinidad and Tobago Coast Guard. Two Spica class variants CG40 built at the Karlskrona ship yard in 1979 - 1980. TTS Barracuda and TTS Cascadura.

[@IkeCrow]

I was a radist in Turunma during the sailing season in 1980. A great place to military service. Shooting the main weapon was felt in the whole ship. We visited Kiel. During the Navy Week, there were ships from many countries. Turunmaa was one of the smallest ships, but probably had the largest main gun (120 mm).

[@dawnsparrow4477]

A wonderful video about Turumaa class corvette..battleships for Finland 🇫🇮 naval forces..video clearly explained all characteristics of this battleship..also video clearly explained progressing steps of Finland 🇫🇮 navy and political background of these upgrade steps of Finland 🇫🇮 navy, thanks ( weapon detective)channel for sharing this video

[@davequinn2369]

Great vid mate. All the best.

[@cwf_media9200]

I can't wait I love the European tiger weapons way too much in combination with weapon detective

[@capehookrennsport7696]

Nice video, I just happened to find it. I did my military service onboard FNS Turunmaa

[@aabaabcbaabcdcba]

08:36 8 rounds per minute? But the clip shows it shooting 8 rounds in 8 seconds. Perhaps you meant 80 rounds per minute.

[@MFitz12]

The spec was80. The closed captioning says 80. Misspoke.

[@jari2018]

That vessle had the Bofors FAK -120 as in naval gun - similar development to the soviet 130mm anti aircraft gun

[@phrog773]

great video! have you considered doing one one the EBRC Jaguar?

[@mikepette4422]

that really is a big gun on a small ship

[@evatanen]

At the beginnnig of the video I had to make sure, that the playback is on normal speed. I thought that it might have been x1.25 ;-)

[@amarjeetbadhani3616]

JAI HIND 🇮🇳 🇮🇳 🇮🇳 Nicely explained.. Just out of curiosity how much time it takes you to prepare one video??

[@WeaponDetective]

Thanks for your interest. Our team has extensive knowledge of weapon systems. As you may have noticed, in a series, we are making six videos each involving air, land and sea systems, respectively. Before starting a series, we decide on the systems of the next series and start detailed study. This gives us a runtime of roughly six weeks for each system. As you may see, we use all six weeks for six videos, not one video. There are also changes that we make at the last moment according to the current events. Naturally, this reduces the preparation time.

[@amarjeetbadhani3616]

@@WeaponDetective wonderful and thanks to provide us quality analysis videos..

[@gregoirelenoel507]

The design makes sense in the context of defending a large coastal area with not enougth budget to maintain large ships in meaningfull number; packing a decent gun on a small hull, yet with smaller (and more agile) weapons allow it to have all the basic capacities, though it would not survive a major engagement on its own; it would still have the capacity to deal damages before geting destroyed, so it at least deters a little from the conflict, while it can travel a decent distance as well. Howether, it has become obsolete in regard to stealth technology, so it still makes sense when getting hiden is not important (anti pirate missions? escort of civilians, show of/assert presence yet without asserting a high level of threat).

[@mikepette4422]

For coast patrols you dont need a big missile punch. A real patrol boat isn't supposed to engage a large surface vessel anyway just report an incursion

[@Joshua_N-A]

120mm main gun, sounds like a modern coastal battleship.

[@dejanvuga8514]

I enjoy your videos. I do have a question: what is the tube on the barrel of naval guns? Cooling? Could you make a video? :)

[@WeaponDetective]

The 23mm gun is air-cooled. Honestly, we could reach any reliable information about the tubes on the barrel. But, we know that the ZU-23-2MR Wróbel-II, the Polish naval version, is water-cooled.

[@akinerbay6345]

My opinion is the pressure release after fire!🤔👍

[@akinerbay6345]

May be is the kickback spring there when fired it kicks right!👍

[@wadethimbey8596]

It may be the fuze timer. When the round goes to the end of the barrel, it will be programmed by a induction coil to detonate at a programmed time.

[@Pectopah123]

Yes it's liquid cooling for 120 mil because these are autocannons with high firing rate.

[@juslitor]

The turunmaa did sail as far as the mediterranean. Not quite open seas perhaps, but still not only limited to shallow waters.

[@anssikuusela5284]

No, it did not.

[@clangerbasher]

I am hearing correctly? The ship could be pushed along solely by the exhaust from the GT's?

[@oz394]

Great video! One question. what are those racks by the 120mm gun?

[@WeaponDetective]

These racks for the illumination rockets

[@oz394]

@@WeaponDetective Thank you!

[@MFitz12]

Bofors 57mm rocket flare rails. Potentially could fire chaff rockets as well. A common feature on Bofors 40mm and particularly 57mm gun mounts in the 60's and 70's.

[@BhriguDRaptor7]

You didnot mention the AK230 CIWS on it that i see in the ship

[@Satunnaistasotilashistoriaa]

There are two ships in parallel on the museum wharf. That one with AK-230 is older minelayer Keihässalmi.

[@gustaveliasson5395]

How many torpedoes can they fit onto that thing? I'm quite surprised to see an ASW ship this small, but if NATO calls it a corvette then Putin's baltic fleet subs better watch out! Edit: ok, so no torpedoes, but enough rockets to keep the russians on their toes. Not bad for a ship of her size.

[@sprocket5526]

with 2.4m draft, that narrow, and what to looks very top heavy. It's must have been a absolute terrible ship to be on in bad weather.

[@MFitz12]

Hence the Vosper stabilizer gear.

[@cra83]

Did they have an open bridge?? A bit outdated and bloody cold!

[@anssikuusela5284]

It was cold only in cold weather 😂

[@chandrachurniyogi8394]

the Scandinavian naval forces of Northern Europe needs to change with time, reform & re evaluate priorities because this ain't the Cold War anymore . . . what this is second Cold War in the making which is about to be even worse than the first one . . . the Viking navies seriously needs to up their game because their adversaries sure are . . . the ongoing 2022 Russian-Ukraine War is solid proof of that in present day situation, post 2020 it's time to go beyond territorial waters because if the Scandinavians don't their adversaries will . . .

[@kk-gr3ly]

If you're referring to the Turumaa vessel, it has been decommissioned for the last twenty years. Highly recommend looking up Nordic Navy's vessels, they're high quality and more than capable to do their job. But the problems lies in the amount of those vessels..

[@mydearcod9639]

Finland don't use this vessels anymore.

[@uncletimo6059]

useless ship

[@kk-gr3ly]

And that is based on what?

[@uncletimo6059]

@@kk-gr3ly it being a useless ship only gun armament, tech from 1940-1950, in a missile era

It was in service from 1969-2002, so of course it is useless now. Missile launchers were not that common at the time it was designed. Hamina class is now in service.

[@kk-gr3ly]

@@uncletimo6059 Did you even watch the whole video??? He clearly stated that it was almost instantly outdated when it was taken into service and specialities it had in that time. And they were decommissioned over 20 years ago..

[@uncletimo6059]

@@kk-gr3ly "He clearly stated that it was almost instantly outdated when it was taken into service" YES. So...... useless ship

[@APerson-lk3ys]

I mean okay its a gunboat... nothing special. A few ASM (Anti-ship missiles) would knock it out of the water, and a fast boat swarm would.. swarm it.. drones would pulverize it. So... ?

[@kk-gr3ly]

This was in late 60s/early 70s.. There wasn't such things as drones.. The Turunmaa was more than capable of dealing with small boats and light targets...Did you even watch or listen to the video? You should know what made this "special". Maybe you should have listen to the video more carefully rather than jumping in to conclusions. And also The Turunmaa class was decommissioned in 2000...

[@Pectopah123]

ASM? In archipelago? Its harder as it sounds. Open sea maybe, but 1960's missiles were not so good for this size target.

[@MFitz12]

Someone plays too many video games and is also ignoring the timeframe.

[@matsv201]

"fast boat swarm" With two bofors 40mm and a fully automatic 120 that can be loaded with flak...
