Kampvogn m/45 "Riksvognen"

After The Third Reich capitulated The "Kampvogn" Project was issued an order from the army. To scavange any surviving German tanks and research their tech. This order led to a rare find, an abandoned  Panzerkampfwagen Tiger Ausf. B or commonly known as the Tiger II.
After some time Norwegian researchers had a technical profile of the Tiger II. As the war between Sweden was still going and they where using German tech themselves, they designed a Heavy tank that would rival the Tiger II. The Kampvogn M/45 was the result of that.
Due to Norway having little experience with heavy tanks at this caliber, many field modifications where made to the tank and even at one point removing the top hull and modifying it to give he suspension more room to work.
The reverse engineered KwK gun ran into multiple issues when used on the field. The gun was prone to shell ejection issues and would result in the whole gun having to be taken out and dismantled to remove the shell. This was fixed pretty quickly.
The production of the Kampvogn m/45 led to the creation of the tooling needed to produce the Forsvarsvogn m/45 No.1 - 3.
