Basilan Viva Portmasters

The Basilan Steel was founded as one of sixteen expansion teams for the MPBL's 2018–19, as one of five expansion teams from the Visayas and Mindanao. The team was originally going to be called the Basilan Shooters, but was renamed since it may be associated with violence. Their application was accepted by the league in May 2018 who reasoned that they want to show the beauty of Basilan "through basketball".

In the 2018–19 season, the team finished with a 7–18 record, giving the team the second-worst record in the South Division. In the 2019–20 season, Basilan won 20 of the 30 games that season, awarding them with the division's third seed. After defeating Iloilo and then Bacoor City, the team reached the division finals against the Davao Occidental Tigers.

The series was tied 1-1 before the COVID-19 pandemic suspended the playoffs for one year. When the league resumed play with a bubble in Subic, Basilan had some of its players tested positive for COVID-19, thus ruling them out of the bubble and putting an abrupt end to the season. Davao Occidental would go on to advance to the national finals and eventually win the championship.

Basilan moved to the Pilipinas VisMin Super Cup as one of its inaugural teams, going by the name Basilan Peace Riders, marking the team's first professional stint. After going undefeated in the Mindanao leg of the 1st Conference, Basilan was granted an instant berth into the Mindanao finals against the fourth-seeded Roxas Vanguards. The Peace Riders swept the Vanguards to advance to the First Conference finals against KCS Computer Specialist – Mandaue. In the best-of-five series, Basilan beat Manduae 3–0 to win their first-ever league championship.

The team returned for the 2021 Invitational, going by the name Basilan Jumbo Plastic. The team was given the group's first seed as a reward for winning the Pilipinas VisMin Super Cup 1st Conference. After defeating Mindoro and Pasig, the team made it to the winner-takes-all finals against the Nueva Ecija Rice Vanguards. With 1.9 seconds remaining in overtime and the score tied at 80, Philip Manalang made the championship-winning buzzer beater to give Basilan the MPBL Invitational title.

The Basilan Steel transferred yet again, this time to the Pilipinas Super League alongside the Davao Occidental Tigers. In the 2022 Pearl of the Orient Cup, Basilan finished on 8–6 and ranked 4th. In the semifinals, Basilan faced the first-seeded Davao Occidental, but was swept in the series. The team then lost the third-place game against second-seeded Roxas Vanguards.

On November 27, 2024, in an interview with Snow Badua on SPIN.ph, Sumisip mayor Julz Hataman announced the revival of the Basilan franchise and its full-time return to the MPBL. Funding the team's comeback to the regional league was shipping company Starhorse Shipping Lines.

Ahead of the 2025 season, the team acquired PBA veterans Alex Cabagnot and Arwind Santos as well as all-stars Rabeh Al-Hussaini, Emman Calo, and Jeff Viernes to join the returning team. The team also appointed Mac Tan, who won the inaugural MPBL championship with the Batangas City Athletics, as the head coach. Former PBA players Rich Alvarez and Rob Labagala also join the coaching staff as two of four assistants. Mid-season, the team also acquired Greg Slaughter, who was previously with the Manila SV Batang Sampaloc in 2024.
