Piraya (Swedish for piranha) is the name of an unmanned surface vehicle project under development by the Swedish shipyard company Kockums AB in collaboration with the Swedish military. The project is a small size boat with a 20 horsepower engine that runs without a human crew. The biggest difference between the Piraya and other unmanned surface vehicles is that several Pirayas can be operated at the same time by a single person. The vehicle has stealth capability just like the larger Visby class corvettes. The vessels will be equipped with infrared sensors and hydrophones.
Displacement 400kg
Length 4 meters
Beam 1,4 meters
Propulsion diesel or gasoline 20hp engine.
Speed +20 knots

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.

![Pansarbil FM/29 Walkaround - Swedish Interwar Experimental Armored Car From 1927 [2.7K]](https://i.ytimg.com/vi/Mv6uwiNKm6o/mqdefault.jpg "Pansarbil FM/29 Walkaround - Swedish Interwar Experimental Armored Car From 1927 [2.7K]
[2.7K] Pansarbil fm/29 is a Swedish made light armoured car which served the Swedish armed forces inbetween 1930-1945 and it was primarly used as a experimental vehicle for various of tests conducted by the Armed forces. Till the start of the 1940’s, when it was also introduced as a “Driving school car” for the K1 Regiment (K1 Livgardets dragoner Regementet) for new potential drivers for the m/39 and m/40 armoured cars. Even late as 1946, the Pbil fm/29 was still on the vehicle records of the Swedish Armed Forces.

Gun: 37 mm cannon w/1898

Crew: 4-5
Speed: 60 km/h
Constructed: 1930
No. built: 1
Pansarbil fm/29 was first introduced to the Swedish Armed forces in 1927. When the Goverment permitted a 10 Thousand SEK budget (Which is equallent to around 300000 SEK (or 30 thousand USD) in today’s value), in a attempt to find a provisional solution to design a domestic “armoured car tactic”. The original plan was to import foreign armoured cars and incorporate them to the Armed forces. However, there were no suitable foreign design to solve the demad. And so the Swedish Armed Forces opted for a domestic design and production of armoured cars within Swedish Territory.
One of the main requirements for the design of the armoured car, compared to the others which were produced in Tidaholm (Pansarbil fm/25 and fm/26 4): Were the ability to be able to drive off-terrain in certain scenarios. The Pavesi P4/100 Artillery tractors were initally purchased from Italy as a reference for the design of the vehicle. The Chassis design were handed to the “Artilleridepartementets konstruktionsavdelning” at KAF (Kungliga Arméförvaltningen), in which the final drawings of the design was completed in July 1930. The task of proucing said Chassis however, was handed over to AB Landsverk, which had it’s background in the construction of railway carriages, elevators and even pumping stations. By June 1931, the chassis for the armoued car was completed
Pansarbil fm/29 has two stearing wheels, meaning it can drive up to 60km/h in both directions.
However, at the same time as AB Landsverk was done with the Chassis. The construction/production of the armoured protection and hull of the vehicle was being made at the Manufacture Department of the “Artilleridepartementet”. This armored body consisted of riveted plates (or regular industry steel) with a thickness of around 4-6mm. Bofors also helped with the design by giving the armoured plates angles in order to improve the overall protection. The wheels of the armoued car was also protected by the riveted plates. Due to it’s abnormal design of the vehicle, many compared it as a glossy monster than a actual armoured car.
About Arsenalen:
The Swedish Tank Museum – Showing the military vehicle development, as well as the military history of Sweden, from the early 20th century until today. The museum also includes a very special exhibition of tin figures, as well as a soldier’s croft dating back to the 17th century, where an accompanying exhibition tells you about a bygone era.
The museum was inaugurated June 17, 2011 and is open year round. Run by a private foundation – Foundation Södermanland Military History collections. The vehicles belong to the Swedish Government – the Swedish National Museums of Military History. The vehicles were previously located to the Tank Museum in Axvall and Military Vehicle Museum in Malmköping. The collection includes about 350 vehicles, of which about 75 are on display in the museum. Some parts of the exhibition changes each year.
Beside the museum there is an original soldiers croft from late 19th century with an accompanying exhibition, The Soldier and the Croft. An exhibition about the history of the local Regiment (Södermanland regiment) tell the story from 14thcentury until 2005 when the regiment was closed. The figure museum is a private collection which previously existed as a museum in Hjortnäs in Dalarna.
