[b][5] The team was founded in 1967 due to a merger of two local sports clubs, Rosenlewin Urheilijat-38 and Porin Karhut.

Ässät has a total of nine medals in the upper tier of Finnish ice hockey, with four of them being silver and two of them being bronze.

When an agreement was finally reached, Rosenlew took over a portion of Karhut's debts and promised to support the new team financially in its early years.

[10] Thanks to inheriting the RU-38 championship, Ässät also played in the 1968 European Cup, where it won its first two rounds before being beaten by SC Dynamo Berlin in the quarter-finals.

The new club did not receive unreserved support from the people of Pori, as the number of spectators decreased by 10,000 from the last season of Karhut.

For the following season, 1969–70, Ässät suffered two heavy losses when Veli-Pekka Ketola and Alpo Suhonen left for Jokerit for a year.

In the final series, everything fell into place, Ässät lost only one of their ten matches and overtook the Helsinki clubs ahead.

The first championship came under the leadership of the forward trio Erkki Väkiparta – Veli-Pekka Ketola – Tapio Koskinen.

[16] For the 1975–76 season, Ässät joined the newly formed SM-liiga, making it one of the original ten clubs in the league.

However, promising young players joined Ässät; Tapio Levo filled the gap left by Rautakallio.

[17] The 1977–78 season again raised hopes of success when Pekka Rautakallio and Veli-Pekka Ketola returned to Ässät from North America.

In addition, promising young people played in the club, such as Arto Javanainen, Kari Makkonen, Tapio Levo and Harry Nikander.

The most important player on the team was the captain, center Veli-Pekka Ketola, who had returned from the North American WHA League.

[22] After the silver seasons, Ässät suffered bad losses when Veli-Pekka Ketola went back to North America.

For the 1983–84 season, the team received well-known returnees when Tapio Levo returned from the NHL and Risto Tuomi and Harry Nikander from Sweden.

The team was also strengthened by its own juniors, from whom more top players of the future were emerging; In addition to Javanainen and Levo, Kari Takko and Christian Ruuttu, among others.

Ässät won 37 of their 44 games in the 1989–90 I-Divisioona season, and played against JoKP in the SM-liiga qualification series, beating them and being promoted back to the league.

[27][28] After the 1997–98 season, Ässät's playing success no longer carried the team into the playoffs, and the following years were quite a toddler at every level of the organization.

Bankruptcy was not far off, and senior officials were arrested on suspicion of tax evasion, although charges were subsequently dropped.

[36] The biggest scandal happened when Sport's coach Juhani Tamminen commented on the series and the whole league system in a press conference.

[47] During the World Championship break in November, Ässät strengthened their team with high-class returnees when Jarno Kärki, who moved to Tappara at the end of the previous season, and Sakari Salminen, who had played abroad for many years, returned.

Ässät sent Lukko directly to the summer holidays with a 2–0 series win and advanced to the semi-finals against Oulun Kärpät.

[59] Rysty Mesikämmen is a brown bear who wears an ice hockey helmet and Ässät's jersey with the number 67.

[62][63] It has become a tradition for ässät fans to sing the ending of the regional anthem of Satakunta, so in 2024, Lukko decided to stop playing it before games.

[73] Currently, the Isomäki Ice Hall is known for its closed atmosphere and reputation as a difficult arena for away teams.

[94] In 2023 after a successful season, the arena got a new jumbotron and new sound technology – increasing the amount of speakers from ten to 130.

Arguably the best female player to come out of the Ässät junior department after the collapse of the senior team is Sofianna Sundelin, Olympic and World Championship bronze medallist who currently plays for St.
