The Tikuna Submarine, type IKL – 209, built by Rio de Janeiro Navy shipyard , presents many improvements developed by Brazilian naval military engineering. Its low noise level, high batteries capacity, resistant hull and easy maneuverability qualify it as a powerful weapon, employed by the Brazilian Navy in shallow and blue waters. The integration of periscopes, inertial navigation system, ESM and sonars to the weapon system, associated with eight torpedoes tubes in forward section, provides fast reaction capability and great operational versatility.


The Niteroi Class Frigate is a ship conceived to operate alone, at a restricted threat environment, or with others surface and aircraft units, in multiple threat scenario, emphasizing naval forces and convoys protection in areas where submarine threat is predominant. Originally designed in two versions, antisubmarine and general purpose, the Niteroi Class Frigates was modernized to improve its defence capacity against missiles and aircrafts attack. Now, she counts with new onboard sensors, Aspide SAM, Mk3 40 mm gun and Siconta MKII Tactical Control, which was developed by the Brazilian Navy Research Institute.


The Barroso Corvette, built by Rio de Janeiro Naval Shipyard, is the head of a new batch of the well-succeeded “Inhaúma” class corvettes. The deployment is the same as “Inhauma” class but many improvements were incorporated such as increased length, improved C3 capacity, helicopter capability, enhanced stealth and discretion, and a better seakeeping attributes. Weapons and sensors configuration were changed in comparison to the “Inhauma” class.


The Macae class Patrol Ship, designed by CMN and constructed in Brazil under management of EMGEPRON, is an offshore patrol vessel, suitable for vigilance missions and police tasks. She can be fitted with state-of-the-art equipment such as surveillance and navigational radars as well as a fire control system. The armament is composed of one medium calibre gun and two small calibre machine guns.


The Grajau class is a versatile ship, designed for patrol operations in territorial and coastal waters, offshore platform protection, combat of drug trafficking, smuggling, illegal fishing, and also search and rescue operations. The ship stands out by its ease operation, good maneuverability and high reliability of systems and armaments. The engines, simple to maintain, develop maximum speed of 27 knots, allowing agile and efficient patrolling.


The MARLIM class Patrol Boat was developed as an answer to the Brazilian Navy requirements for naval police operations. The boat is constructed in aluminium and was designed for patrolling of harbours and coastal areas. A removable light machine gun 7.62 mm was mounted on the bow, but the boat´s structure and stability allow the installation of a fixed 20 mm machine gun. With two V-drive propulsion units, each one powered by a 1000 bhp MTU diesel engine, the boat can reach 25 knots maximum speed with excellent sea-keeping, being capable to navigate in heavy seas with high speed. Due to the V-drive system, all engines compartments are positioned astern, permiting a continuous and spacious arrangement for accommodations. The detection and communication systems are suitable to undertake actions against illegal fishing, drug traffic and smuggler activities. Alternatively, it can also perform emergency rescue operations.


The Rio Class Patrol Boat was designed for coastal surveillance and patrolling of bays and harbours. The hydrodynamic shape of the hull provides excellent acceleration and maneuverability to the craft. Its structure allows the installation of up to .50 inches machine guns in the bow and stern sections, making it highly effective in the repression of several crimes at the sea, such as drug trafficking, smuggling and illegal fishing.


A high speed craft with low draught, designed for fast patrol missions, achieving points situated as far as 200 miles from its Base. Having a planing hull in naval aluminum, optimized in accordance with requirements for hydrodynamic efficiency, it is excellent for military operations like landing of troops on rivers and beaches. It is also adequate for civil applications, such as support to off-shore installations, in ports surveillance, fishing control, waterpollution fighting due environment accidents, and as maritime ambulance. A powerful Diesel engine propulsion system develops elevated torque to produce fast acceleration.


The Ambulance Craft - LAM, built at Val-de-Caes Naval Base, located in Belem, is a versatile boat, suitable for fast removal of wounded on riverine environment. Made of naval aluminium alloy, LAM transports up to two patients and a crew of four men at 30 knots maxi- mum speed. LAM is equipped with facilities such as: removable hammock, oxygen cilinders, portable stretcher for adult and children, 250 litres water tank and reversible seats. It can be also equipped with different medical equipments according to client needs. LAM’s outstanding performance and easy maintenance make it ideal to be employed by health institutions, firefighting brigades, civilian defence corps and private companies.

ET/SLQ-2X, is an advanced shipborne ECM equipment which, together with Defensor ET/SLR-1X ESM forms a jamming system effective against a maximum of eight simultaneous threats (four on each side of the ship, with 360º azimuth coverage). Based on Phased Array technology, it operates with multiple TWT tubes and high voltage power supplies, featuring graceful degradation, even in the event of tube failure. The system is based on DRFM and includes multipolarization transmission and cross-polarization techniques.

ET/SLR-1X is an electronic support measures equipment able to detect and classify up to 100 emissions in 2 to 18 GHz frequency band. It allows automatic/manual target selection for transmission of measured characteristics to electronic counter measures equipments.

The Monitoring & Control System - SCM, developed by Brazilian Navy Research Institute - IPqM, is a propulsion control system integrated to a damage control system. The SCM operates with three subsystems: Propulsion and Auxiliary Control System, Damage Control System and Remote Manual Subsystem. Its flexible and scalable architecture allows the installation of one or more subsystems or the whole system in any type of warship or maritime platform, being a powerful tool for safe navigation.

SICAV, is a damage monitoring and control system, designed by Instituto de Pesquisas da Marinha - IPqM, to be employed in military and merchant ships and off-shore platforms. The system allows an efficient and reliable use of ship sensors information such as flooding, smoke, temperature and watertight door control. It can also include an artificial intelligence aided decision subsystem.

SICONTA, is a tactical and weapons control system that has a high degree of modularity which can be configurated in order to be installed in nearly any kind of ship or submarine, according to the user’s requirements. Small size and simple operation, added to the ultimate technology used in its design, make SICONTA one of the best systems of its class.

MDLS, is a rocket launching system that has as primary mission the ship defense against antiship missiles using for such purpose coordinated decoy rocket launching, and can also be used for torpedoes launching. The system can be assembled from one to fourlaunchers with up to twelve tubes each one, depending on the ship where the system will be installed.

The TTI 2900, is a tactical control system, based on a low cost ruggedized PC-BASED architecture, designed to be used by surface vessels and aircrafts. It allows more efficient use of ship sensors and systems in computer assisted jobs such as Tactical Scenario Compilation, Threat Evaluation and Tactical Response. TTI can operate in stand alone mode, where all incoming data and commands are processed in its own CPU or integrated in a distributed system, where each console is connected to other TTI’s or other systems through a local network.
