Ny avansert undervannsbåt sjøsatt fra Kockum

Dette for de som er interessert i en type undervannsbåt  P-8 må detektere, tracke og senke. Med det mener jeg å si at tilsvarende teknologi må en forvente at både Russland og Kina har. Mulig du har hørt historien om en Gotland klasse som skulle øve sammen med en Task Force, nå Battle Group, ut fra San Diego. Hangarskipet Ronald Reagan var målet. "It (undervannsbåten) created havoc". Den senket alt som var, i følge ryktene. Vel, USN leide inn båten for ytterligere ett år for å forstå hva som traff dem. Gotland klasse er nå utviklet videre i en ny type, A26. Sjekk videoen under. (Red.)

Type A26 submarines being built by Saab will serve Swedish Defence as successors to Gotland-class submarines. Type A26’s mission capabilities include maritime security, covert mine countermeasure, intelligence gathering, surveillance, reconnaissance, covert in hostile areas, anti-submarine warfare, anti-surface warfare, mine-laying, underwater work, and other special operations.
Saab has been contracted by the Swedish Defence Material Administration (FMV) to construct, verify and deliver two Type A26 next-generation submarines for the Swedish Navy. It received an order from the FMV to procure sensor systems for the Type A26 in December 2014.
The FMV further awarded a contract worth Skr7.6bn ($925m) to Saab for the construction, verification and delivery of two A26 submarines in June 2015.
The first submarine’s first steel was cut at Saab’s Kockums shipyard in September 2015. Deliveries will begin in 2022 and continue through to 2024.

A26 submarine design and features

The Kockums A26 submarine’s modular hull structure, made from special steels, offers high-seakeeping performance and operational effectiveness. The X-rudder configuration with four independently controlled control surfaces provides high-manoeuvrability. The submarine requires low operating and maintenance costs.
The submarine is 62m-long and has a draught of 6m and a displacement of approximately 1,800t when surfaced. The Scandinavian design offers spacious and comfortable seating for up to 26 personnel. Two crew members are assigned to the same bunk in rotation based on the hot bunk principle.
The submarine has two pressure-tight compartments and a pressure-tight, mid-tank section. An escape tower on top of the mid-tank section facilitates emergency escape for crewmen.
All applicable management and control systems of the submarine are interconnected through the vessel’s general management services system (GMSS). All subsystems are operated from common multifunctional consoles (MFCs), whereas all major ship systems are controlled through the ship control and monitoring system (SCMS).
The submarine can be upgraded with the installation of a hull section in the forward or aft compartment. The forward section can be equipped with additional space for workstations, accommodation and other equipment. An additional diesel and/or Stirling AIP engine can be placed in the aft section.

Equipment carried on A26 submarine

A large, flexible payload stowage compartment allows carriage of a variety of mission payloads to deliver a high degree of operational flexibility. The pressure-tight containers, unmanned underwater vehicles (UUVs), remotely operated vehicles (ROVs), and reconnaissance and rescue systems can be carried externally.
The submarine employs a 6m-long Multimission Portal™ for the launch and recovery of up to eight divers along with their mission payloads. The UUVs can be deployed in mine searching and clearance operations, and the unmanned maritime vehicles are used to gather acoustic, visual, electronic and communication intelligence data.

Navigation and communications

The Type A26 submarine is equipped with mast-mounted optronic sensor systems, as well as active and passive sonar systems for the identification and detection of threats.
Advanced network-centric communication capabilities enable the submarine to integrate them with other forces on the land, sea and in the air. External communication is provided though radio, hydroacoustic and shore-connected methods.

Weapons suite

The weapon system is managed from a Saab combat management system (CMS) that is connected with the GMSS.

Countermeasures and safety features

The GHOST® Genuine Holistic Stealth technology makes the Type A26 invisible and quiet. The submarine has low hydrodynamic and infrared signatures, and low radar cross-section.
The submarine is resistant to significant shock loads from underwater explosions. It is fitted with mine countermeasures to detect, identify and destruct mines. An emergency, high-pressure, air-blowing system is fitted to help bring the submarine to surface in the event of flooding. The submarine is also equipped with a fire-protection system designed as according to SOLAS requirements.

"The submarine has four weapon tubes and can be fitted with more than 15 53cm weapons."

Propulsion and performance of A26 submarines

The main propulsion system of the Type A26 submarine is fully-integrated Kockums Stirling air-independent propulsion (AIP) system, which burns gasified pure industrial liquid oxygen (LOX) and diesel fuel. The submarine is also equipped with a conventional diesel-electric propulsion system.
The maximum submerged AIP speed of the submarine is more than 6k, maximum continuous snorting speed is 12k, diving depth is more than 200m, mission endurance is 45 days, and operating sea water density is between 1,003kg/m³ and 1,032kg/m³. The submarine can withstand temperatures ranging from -2°C to 32°C.
