OVERVIEW: The DM19A2 Flare, also known as the Mk245 A2 GIANT, is an infrared (IR) decoy designed to protect naval vessels from heat-seeking missiles. It is part of the GIANT family of 130mm IR countermeasures, used in SRBOC and other dispensers to create a ship-like spectral signature across all IR wave bands.

DETAILS: This flare is an evolution of the DM19A1, with improvements in spectral adjustment to counter modern infrared missile seekers, including imaging IR-seekers (IIR). It is commonly deployed alongside other naval decoys, such as Mk214 Seduction Chaff and Mk251 Siren Active Decoy
