The Estonian Maritime Museum (Eesti Meremuuseum) is a collector, preserver, researcher, and presenter of Estonian maritime culture (maritime history). “Our mission is to increase people’s knowledge, respect, and love for the sea.”
The Estonian Maritime Museum was established in Tallinn in 1935 on the initiative of former captains and sailors. Throughout its long history, the museum has undergone several changes. The museum’s main exhibition has been located since 1981 in the Paks Margareeta artillery tower, which has a history of nearly 500 years. The Maritime Museum opened its second exhibition space in May 2012 at the Seaplane Harbour.
Currently, the Estonian Maritime Museum is one of the largest museums in Estonia and is also the most popular museum, especially thanks to the Seaplane Harbour exhibition.
In the seaplane hangar at Seaplane Harbour,you can find the Lembit submarine, built in 1937 at the Vickers-Armstrong shipyard in England, the Short 184 seaplane, the wreck of the Maasilinn ship (which is the oldest wreck found in Estonian waters), as well as many authentic exhibition items such as sailboats, boats, and sea mines. Additionally, the museum features the MARU café and museum shop, cinemas, simulators, a children’s area, and many other interesting attractions. In addition to the permanent exhibition, various seasonal exhibitions related to maritime and its history are also open.

K9 Thunder Moukari
In July 2016, the Finnish Ministry of Defence announced that an undisclosed number of used K9s have been selected to be acquired from the Republic of Korea. The acquisition is claimed to be biggest of the decade for the Land Forces, whose both mobile and towed artillery face mass outdating in the 2020s. In February 2017, the Ministry of Defence announced that Finland will acquire 48 used K9s over a period of seven years starting in 2018, with conscript training on the equipment commencing in 2019. In November 2022 Finland announced to buy 48 more K9s. After delivery of all weapons Finland will have 96 K9 SPGs.
The K9 Thunder is a South Korean self-propelled 155 mm howitzer developed by Samsung Techwin for the Republic of Korea Armed Forces and now manufactured by Hanwha Land Systems. It was developed to supplement and then replace the K55 self-propelled howitzers in South Korean service.
K9 is an indigenous system of an all-welded steel armour construction which is rated to withstand 14.5 mm armour piercing rounds, 152 mm shell fragments, and anti-personnel mines. The main armament consists of a 155 mm/52 caliber ordnance with a maximum firing range of 40 km; the K307 BB-HE projectile propelled by the K676 top charge has a muzzle velocity of 928 m/s (3,040 ft/s). State-of-the-art mobility subsystems include a 1,000 horsepower (750 kW) engine with potential for growth and hydropneumatic suspension unit, a requirement for Koreas rugged mountainous terrain.

K9 Thunder on Korean tasavallassa Samsung Aerospace Industriesin ja Korean tasavallan asevoimien vuosina 1989-1998 kehittämä ja 1999 sarjatuotantoon otettu raskas panssarihaupitsi, jonka valmistaja on nykyään nimeltään Hanwha Land Systems. Se on kehitetty aluksi täydentämään amerikkalaiseen M109-panssarihaupitsiin pohjautuvaa korealaista K55-panssarihaupitsia, ja myöhemmin korvaamaan sen kokonaan. K9-panssarihaupitsit muodostavat laajemman tykistöasejärjestelmän samaan alustaan pohjautuvien panssaroitujen K10-latausvaunujen kanssa, jotka kykenevät kuljettamaan lisäammuksia yli kahden K9-panssarihaupitsin ammustäytön verran.
Heinäkuussa 2016 Suomen puolustusministeriö kertoi hankkivansa tuntemattoman määrän K9 Thunder -panssarihaupitseja Maavoimille. Hankinnan väitetään olevan suurin 2020-luvulle tehtävistä vanhan kaluston korvaamisista. Marraskuun lopulla Rovajärvellä pidetyssä Maavoimien vaikuttamisharjoituksessa (MVH16) oli testissä K9 Thunder. Testin tuloksiin ollaan tyytyväisiä. Myöhemmin määräksi tarkentui 48 yksikön telahaupitsin tilaus. Marraskuussa 2022 Suomi ilmoitti ostavansa 48 yksikköä lisää. Toimitusten päätyttyä Suomella on 96 K9-panssarihaupitsia.

Stridsvagn 103
Swedish cold war main battle tank
The Stridsvagn 103 (Strv 103), also known as the S-Tank, is a Swedish post-WWII main battle tank. It is known for its unconventional design: it is turretless with a fixed gun traversed by engaging the tracks and elevated by adjusting the hull suspension. While turretless armoured fighting vehicles are usually classified as assault guns or tank destroyers, despite its unique gun layingprocess, the Strv 103 is considered a tank because its designated combat role matched those of other tanks within contemporary Swedish doctrine. It is the only mass-produced tank since World War II to dispense with a turret.
The Strv 103 was designed and manufactured in Sweden. It was developed in the 1950s and was the first main battle tank to use a turbine engine. The result was a very low-profile design with an emphasis on survivability and heightened crew protection level. Strv 103s formed a major portion of the Swedish armoured forces from the 1960s to the 1990s

T-34/85
Finnish use: Seven tanks were taken to Finnish use during Continuation War. First T-34/76 was taken to Finnish use in October of 1941. The last of these tanks remained in Finnish use until year 1961. The tanks were both captured in combat and brought from Germany.
Finnish estimates and experiences:
Early Finnish estimate of T-34 tank: Armour quite adequate, diesel-engine works reliably even in winter, speed quite adequate - apparently the tank has a good off-road mobility. Our troops have succeeded destroying these tanks with satchel charges thrown to rear deck. Tank crew has poor visibility outside, tank tracks can be broken with satchel charges, antitank-mines or with 37-mm antitank-guns. 45-mm antitank-gun can penetrate lower side hull armour between road-wheels or if the tank is tilted suitably (turning sloped side hull armour into vertical position) it can penetrate also higher side armour.
Finnish tank crews found T-34/76 to obviously be a massive improvement over earlier tanks like T-26E and captured Soviet T-26. Not only was its 76-mm tank gun much more effective and armour protection useful against Soviet antitank-weapons, but thanks to wide tracks, powerful diesel engine and showed good mobility in typical Finnish terrain and also deep snow. Unlike with light tanks even individual tree or two were no real obstacle, since T-34 was found capable knocking down trees less than 80-cm thick. Since the number of captured T-34 tanks taken to Finnish use remained always very limited, it seems likely that most capable crews were handpicked for them. As mentioned the first three T-34 tanks taken to Finnish use were issued to Heavy Tank Company of Tank Battalion and when the Battalion was expanded to Brigade, they went to 3rd Tank Company (1st Battalion) of Tank Brigade. When additional T-34 tanks were received in summer of 1944 also they ended up to this tank company.
