It will equip the KS-III submersible with the Pegaso electronic warfare system
The Spanish multinational Indra has signed a contract to equip the first KSS III submarine of Lot II to be delivered to the Korean Navy with its Pegaso electronic defense system, which offers a high capacity for interception of adversary signals.
The company explains that the system that the new Korean submarine will carry monitors the electromagnetic signals emitted in its environment to collect intelligence (SIGINT), combining the functions of the radar and communications signal measurement support system (RESM / CESM). The solution integrates both sensors in a single antenna to increase its efficiency, save space and reduce the radar section of the submarine itself, making it difficult for the enemy to detect it.
It also incorporates a true wideband digital reception, or ‘True Wideband Digital Reception’, which instantly covers a wide spectrum of the radar and communications band to increase the probability of interception of any ship or aircraft that is in the submarine’s environment. up to practically 100%. The technology adds that, in addition to collecting high-value intelligence information for the entire fleet, the ‘Pegaso’ system will provide data “of vital importance” for the command decision-making process and the tactical planning of the operation to be executed by the rest of the deployed platforms.
Indra will address the high-level integration of its ‘Pegaso’ system with the combat system (CMS) developed by the local Korean company Hanwha Sytems. It will also work with the DSME shipyard in supporting the Korean Navy for the definition of the doctrine of use of electronic defense systems on underwater platforms, particularly in the area of communications signals intelligence in conflict areas.
The Spanish company has been awarded this contract after having equipped three KSS III submarines from the first batch of this program. The new configuration of the ‘Pegaso’ system that it will now implement will be more sophisticated and will increase the capabilities of the new, improved version of the KSS III, a next-generation submarine of about 90 meters in length and capacity to displace more than 4,000 tons submerged.
Military intelligence missions
The ‘Pegaso’ system is capable of automatically and instantaneously carrying out the detection of emissions (including precise information on their angle of arrival), the analysis, classification, identification and recording of pulsed or continuous wave signals in the frequency bands radar and communications.
It also allows to record signals, data and events occurred in the mission for a later offline analysis using specific software tools for the detailed analysis of the mission.
