Tacoma Defiance

Seattle Sounders FC announced the creation of their reserve team on October 14, 2014, at an event held at the Chihuly Garden and Glass museum in Seattle. The new team would be named Seattle Sounders FC 2 (shortened to S2) and play in USL Pro, the second tier of American soccer that the Sounders played in until 2009. S2's home matches were to be played at the MLS team's training facility, the Starfire Sports Complex in Tukwila, beginning in the 2015 season. The Sounders intended to primarily use the team to develop young players and split ownership to a non-profit, fan-owned organization called the Sounders Community Trust. A similar reserve team for the Portland Timbers, T2, was also announced on the same day. Sounders assistant coach Ezra Hendrickson was named the team's coach on November 13, 2014. Inaugural season S2 played its inaugural match on March 21, 2015, winning 4–2 over the defending USL champion Sacramento Republic. Andy Craven notched the first goal in team history. Their second game yielded the team's first shutout, a home game against Whitecaps FC 2 that ended 4–0. Darwin Jones scored the team's first hat-trick during the game. Tacoma relocation The owners of the Tacoma Rainiers baseball team had expressed interest in hosting a lower-division soccer team at its ballpark, Cheney Stadium, or a separate soccer stadium as early as 2013. Cheney Field hosted an MLS Reserve League match between the Sounders and Orlando City SC reserve teams in May 2013, which brought an attendance of 2,174. The Rainiers partnered with the Tacoma Stars, an indoor soccer team, and discussed a potential move for S2 with the Sounders organization. The Sounders had previously discussed plans to move their lower-league franchise to the Tacoma area in the 2000s in the event of a successful MLS expansion bid. On May 6, 2017, the Sounders and Rainiers announced that they had agreed to relocate the reserve team to Tacoma upon completion of a new, 5,000-seat soccer-specific stadium by 2020. After the USL announced its intention to refuse waivers for teams with smaller venues that did not meet full Division II requirements, the Sounders announced in November 2017 that S2 would temporarily play at Cheney Stadium in Tacoma beginning in the 2018 season. The team had previously played in front of crowds of less than 1,000 at Starfire Sports, but debuted at Cheney Stadium with a sellout crowd of 6,049 on March 16, 2018. The team failed to qualify for the USL playoffs, but the first season in Tacoma garnered an average attendance of over 3,000. The club was re-branded as the Tacoma Defiance on January 30, 2019, following a campaign to solicit suggestions from the public for a new name. The Defiance name was the top choice in the poll and references Point Defiance Park and Tacoma's civic pride. MultiCare Health System was named as the team's jersey sponsor and Reign FC of the National Women's Soccer League also announced a move to Cheney Stadium for the 2019 season. Sounders FC Academy Director Chris Little had been named as the team's new head coach a week earlier, replacing John Hutchinson. MLS Next Pro The club announced on December 6, 2021, that it was joining the inaugural 21-team MLS Next Pro season starting in 2022. As a result of Minor League Baseball rules rendering Cheney unavailable, and the abandonment of the Tacoma soccer stadium project, the Defiance relocated back to Starfire. ==Team colors and crest==

The Tacoma Defiance branding was unveiled on January 30, 2019, replacing the original S2 brand that was inherited from the Sounders. The name references Point Defiance Park, a major park with gardens, a zoo and aquarium complex, and several marinas. The club's crest is a black circle featuring an image of a stylized ship, based on , in the foreground and the tentacles of a Giant Pacific octopus surrounding it. The original team colors for S2 were inherited from the first team, including the Sounders' trademark Rave Green. The crest was a green silhouette of the Sounders crest, itself constructed with symbolism representing the club, fans, and players, with "S2" in the center. The club continues to use the basic silhouette in their secondary mark, with "TAC" in the center to represent Tacoma. A tertiary crest includes the words "Defiantly Tacoma". ==Stadium==

S2 initially played its home matches at Starfire Sports Complex's main stadium, which seats 3,500 spectators and is located in the suburb of Tukwila, Washington. The complex was also used by Seattle Sounders FC for training and non-MLS matches as well as the club's academy teams. The largest attendance for an S2 game at Starfire was 2,951, set on March 21, 2015. By the 2017 season, the team was averaging below 1,000 spectators for matches at Starfire. For soccer matches, the pitch was aligned to the third base line, the pitcher's mound was removed, and the dirt infield was filled with grass. S2 would continue training at Starfire in Tukwila alongside the first team. S2 was renamed to the Tacoma Defiance in 2019 amid plans to build a permanent soccer-specific stadium for them and the NWSL's OL Reign, who had also moved to Cheney Stadium. The stadium would seat 5,500 spectators and cost $300 million to develop on city-owned land adjacent to Cheney Stadium. The preliminary plan for the stadium complex, which would open in 2021, was approved by Metro Parks Tacoma in 2018; work on the complex was suspended in 2020 during the COVID-19 pandemic but was later expanded to a larger stadium to meet NWSL requirements. OL Reign later moved back to Lumen Field in Seattle for the 2022 season and left the stadium project. The Defiance played all but two of their home matches in the inaugural season of MLS Next Pro at Starfire Sports in Tukwila due to a revision to minor league baseball requirements that made the conversion of Cheney Stadium for soccer matches more complicated. The team moved all of their home matches to Starfire for the 2023 season. The Defiance moved their home matches and training facilities to the new Sounders training center in Renton at Longacres in 2024. ==Ownership and team management==

The ownership of the club is composed of two groups. The majority owner is the Sounders FC organization, with the non-profit Sounders Community Trust owning minority share of 20%. Andrew Opatkiewicz was hired as the General Manager in October 2014, having experience with Seattle Wolves FC (now Washington Crossfire). Retired MLS veteran defender and former Assistant Coach and Reserve team coach of Seattle Sounders FC, Ezra Hendrickson, was announced as the head coach of S2 on November 13, 2014. Opatkiewicz took an indefinite leave of absence from the team in May 2016 and Kurt Schmid, the former Seattle Sounders FC head scout and son of then-coach Sigi Schmid, was named as S2 GM on an interim basis. Chris Little was named the head coach of S2 shortly before its rebranding as the Defiance in 2019. Webber left the position in November 2023 and was replaced two months later by Hervé Diese, a former assistant coach for CF Montreal and Angel City FC. In February 2026, the Defiance named Paulo Nagamura as their new head coach and recently retired Sounders midfielder João Paulo as an assistant coach. ==Players==
