[2] CD Dragón have played their home games at the 10,000 capacity Estadio Juan Francisco Barraza since 1956 when the stadium was built.

Under the coaching of player-coach Esteban Blanco, the direction of Samuel Córdoba and key players such as Juan Francisco Barraza, Rómulo Granados and Domingo Flores, the club experienced their most successful period in the 1950s, when they won two league titles (1950–51, 1953–53) and lost two other championship finals.

Águila began to assume the mantle as the top representative of San Miguel and began to drain Dragón of quality players such as (Barraza, Blanco and others), sponsorship and fans which led to Dragón not only developing a fierce rivalry with Águila but also led to the club being relegated to the Second Division after the conclusion of the 1963–64 season.

[5] Mario Martínez, whose name will become entwined with Dragón, helped the club gain promotion to the First Division thanks to a 2–1 aggregate victory over Halcón de San Cayetano Istepeque, during this period a new crop of talented players were identified including future highest goalscorer for the El Salvador national football team Raúl Díaz Arce, Moisés "Pecho de Mono" González, and others.

Dragón won promotion to the First Division mainly due to the coaching of Mario Martínez second time in which he helped C.D.

[6] Despite having a very poor Apertura campaign in which Mario Martínez was sacked and replaced by Nelson Ancheta, with the recruitment of club legend Williams Reyes and the emergence of stars like Rommel Mejía, Santos Ortíz, and Aurelio Vásquez the club reached the Clausura grand final (after disposing Santa Tecla in a play-off series 2–1, and defeating league leaders FAS in the semi-finals 1–0 on aggregate), However, despite the game ending 0–0 after 120 minutes, two missed penalties in the shootout meant that Isidro Metapán would win the grand final 6–5 on penalties.

However, despite winning their first championship in 63 years their fortune dwindled first showed a poor international performance at the concacaf losing 3 games and drawing one, with 6–0 loss against Deportivo Saprissa being the worst of the result.

Dragon won the Clausura 2022 tournament defeating Inter SS 2-1, with the goals coming from Javier Fermán and Henry Álvarez.

[8] On 6 June 2022, after 4 years out of the Primera Division, Dragon were promoted back to the top flight following a 4-2 playoff victory against Apertura 2021 champion AD Municipal 4-2 with goals coming from Kevin Moreno, Henry Álvarez and a double from Romel Mejía.

[9] Dragón plays its home games at Estadio Juan Francisco Barraza located in San Miguel, The stadium has a capacity of 10,000 people.

The intense feelings between the two sides began early on due to the close proximity and the switching of players between the clubs.

The biggest defection occurred in the 1950s when legendary players Juan Francisco Barraza, Esteban Blanco and left the championship side of Dragon to Aguila and started a dynasty.
