Danilo Atienza Air Base (IATA: SGL, ICAO: RPLS) is a military base used by the Philippine Air Force, located on the northern end of the Cavite Peninsula in Manila Bay, Luzon Island, Philippines.

During the brief period of combat between loyalist and revolutionary elements of the military, a squadron of four F-5A's led by Major Danilo Atienza repeatedly bombed and strafed Sangley Point Air Base, destroying several T-28 combat planes belonging to the coup forces.

In 2013, the All-Asia Resources and Reclamation Corporation (ARRC) — a venture headed by tycoon Henry Sy — commissioned Danish construction firm Rambøll Group A.S. to conduct a feasibility study for the reclamation of 50 hectares off Sangley Point and the development of an airport with two runways and a terminal capable of handling 50 million passengers annually in place of the current air base.

[5] The entire ARRC project involves the construction of an airport and seaport facility, as well as an industrial complex (ecozone), on land reclaimed from Manila Bay off Sangley Point;[5] it is estimated to cost US$50 billion, involving among other things the reclamation of a total of 2,500 hectares of land[6] and the construction of either an underwater tunnel to the SM Mall of Asia complex in Pasay or an extension of the Manila–Cavite Expressway to connect the project to Metro Manila.

[7] In December 2016, the ARRC also proposed to the Duterte administration a plan to develop the existing Danilo Atienza Air Base and its 2.4 km long runway into a facility for low-cost carriers and general aviation "while waiting for the new airport.
