The name Armada was given in 1987 at a bar in the "Ri" shopping mall in Rijeka, and the first game attended by the Armada was the Final of the Yugoslav football cup against Hajduk Split in Belgrade on the 9th of May 1987. The newly formed supporters group named themselves after the Spanish Armada because of the strength they showed in their support. Their fiercest rivals are BBB (Bad Blue Boys), Torcida and Kohorta.
At home games, Armada members gather in the west stand at Stadion Kantrida, from where they fiercely support their club. They also regularly support Rijeka in the club's away games. They regularly display choreographies and light up flares.
Their mottos are: Sami protiv svih - Alone against everybody, and Krepat, ma ne molat - Die but not give up.
There are numerous Armada murals around the city of Rijeka, and its surroundings, showing each neighbourhood's support and love for the club. The murals, which can be classified as a form of urban art, stretch from Pasjak near the border with Slovenia, in the north, to Novi Vinodolski in the east, Malinska, on Krk island, in the south, and Lovran in the west. The location and photos of murals can be found on Armada's official website.
