With Scott Cronce. Go on missions with a Los Angeles class 688 Attack Sub, during the cold war. Alternately you can play as a Soviet Alpha class submarine. Go through training missions, espionage missions, and finally actual combat as the cold war turns hot.

Los Angeles-class SSN profileThe Los Angeles class boats are in service with the. The submarines are also known as the 688 class (pronounced 'Six-Eighty-Eight'), after the hull number of lead vessel. They represent two generations and close to half a century of the Navy's attack submarine fleet.

As of 2018, 35 of the class are still and 27 are retired from service. Of the 27 retired boats, 12 were laid up half way (about 20 years or less) through their projected lifespans, and another five also laid up early (20–25 years), due to their being cancelled,.

Seven have been scrapped and two are being converted to. A further four boats were proposed by the Navy, but later cancelled. The class has more active nuclear submarines than any other class in the world.

Submarines of this class are named after American towns and cities, such as;, California; and, with the exception of, named after a US Navy. This was a change from long-standing tradition of attack submarines after marine animals, such as or.In 1982 after building 31 boats, the class underwent a minor redesign.

The following eight that made up the second 'flight' of subs had 12 new vertical launch tubes that could fire. The last 23 had a significant upgrade with the 688i improvement program. These boats are quieter, with more advanced electronics, sensors, and noise-reduction technology. The are placed at the bow rather than on the, and are retractable.

Crewmen monitor consoles at the diving station aboard a Los Angeles-class submarineAccording to the, the top speed of the submarines of the Los Angeles class is over 25 (46 km/h; 29 mph), although the actual maximum is classified. Some published estimates have placed their top speed at 30 to 33 knots (56 to 61 km/h; 35 to 38 mph). In his book Submarine: A Guided Tour Inside a Nuclear Warship, estimated the top speed of Los Angeles-class submarines at about 37 knots (69 km/h; 43 mph).The U.S.

Navy gives the maximum operating depth of the Los Angeles class as 650 ft (200 m), while, in his book Running Critical, suggests a maximum operating depth of 950 ft (290 m). Although Tyler cites the 688-class design committee for this figure, the government has not commented on it. The maximum diving depth is 1,475 ft (450 m) according to Jane's Fighting Ships, 2004–2005 Edition, edited by Commodore Stephen Saunders of the Royal Navy. A portside bow view of the fore section of tied up at the pier in February 1994: The doors of the Mark 36 vertical launch system for the Tomahawk missiles are in the 'open' position.Los Angeles-class submarines carry about 25 -launched weapons, as well as Mark 67 and Mark 60 CAPTOR and were designed to launch, and horizontally (from the torpedo tubes). The last 31 boats of this class (Flight II/688i) also have 12 dedicated tubes for launching Tomahawks. The tube configuration for the first two boats of Flight II differed from the later ones: Providence and Pittsburgh have four rows of three tubes vs.

The inner two rows of four and outer two rows of two tubes found on other examples.Control systems Over close to 40 years, the control suite of the class has changed dramatically. The class was originally equipped with the Mk 113 mod 10 fire control system, also known as the Pargo display program. The Mk 113 runs on a computer.The Mk 117 FCS, the first 'all ' replaced the Mk 113. The Mk 117 transferred the duties of the analog Mk 75 attack director to the UYK-7, and the digital Mk 81 weapon control consoles, removing the two analog conversions, and allowing 'all digital' control of the digital mk 48 control.

The first 688 sub to be built with the Mk 117 was.The Mark 1 Combat Control System/All Digital Attack Center replaced the Mk 117 FCS, on which it was based. The Mk 1 CCS was built by, and gave the class the ability to fire Tomahawk missiles. The CSS internal tracker model provides for both and spherical-array trackers.

Are signal followers that generate bearing, arrival angle, and frequency reports based on information received by an acoustic sensor. It incorporated the Gyro Static Navigator into the system in replacement of the DMINS of the earlier 688 class.The Mk 1 CCS was replaced by the Mk 2, which was built.

Mk 2 provides Tomahawk Block III vertical launch capability as well as fleet-requested improvements to and Towed Array Target Motion Analysis operability. The Mk 2 CCS paired with the AN/BQQ-5E system is referred to as the QE-2' system. The CCS MK2 Block 1 A/B system architecture extends the CCS MK2 tactical system with a network of tactical advanced computers (TAC-3). These TAC-3s are configured to support the SFMPL, NTCS-A, LINK-11 and ATWCS subsystems.Sensors Sonar AN/BQQ-5 sensor suite consists of the AN/BQS-13 spherical sonar array and AN/UYK-44 computer.

The AN/BQQ-5 was developed from the AN/BQQ-2 sonar system. The BQS 11, 12, and 13 spherical arrays have 1,241 transducers. Also equipped are a conformal hull array with 104 to 156 hydrophones and two towed arrays: the TB-12 (later replaced by the TB-16) and TB-23 or TB-29, of which there are multiple variants. There are 5 versions of the AN/BQQ-5 system, sequentially identified by letters A-E.The 688i (Improved) subclass was initially equipped with the AN/BSY-1 SUBACS submarine advanced combat system that used an AN/BQQ-5E sensor system with updated computers and interface equipment. Development of the AN/BSY-1 and its sister the AN/BSY-2 for the was widely reported as one of the most problematic programs for the Navy, its cost and schedule suffering many setbacks.A series of conformal passive hydrophones are hard-mounted to each side of the hull, using the AN/BQR-24 internal processor.

The system uses FLIT (frequency line integration tracking) which homes in on precise narrowband frequencies of sound and, using the Doppler principle, can accurately provide firing solutions against very quiet submarines. The AN/BQQ-5's hull array doubled the performance of its predecessors.AN/BQQ-10 The AN/BQQ-5 system was replaced by the AN/BQQ-10 system.

Acoustic Rapid Commercial Off-The-Shelf Insertion (A-RCI), designated AN/BQQ-10, is a four-phase program for transforming existing submarine sonar systems (AN/BSY-1, AN/BQQ-5, and AN/BQQ-6) from legacy systems to a more capable and flexible COTS/Open System Architecture (OSA) and also provide the submarine force with a common sonar system. A single A-RCI Multi-Purpose Processor (MPP) has as much computing power as the entire Los Angeles (SSN-688/688I) submarine fleet combined and will allow the development and use of complex algorithms previously beyond the reach of legacy processors. The use of COTS/OSA technologies and systems will enable rapid periodic updates to both software and hardware. COTS-based processors will allow computer power growth at a rate commensurate with the commercial industry. Engineering and auxiliary systems Two watertight compartments are used in the Los Angeles-class submarines.

The forward compartment contains crew living spaces, weapons-handling spaces, and control spaces not critical to recovering propulsion. The aft compartment contains the bulk of the submarine's engineering systems, power generation turbines, and water-making equipment.

Some submarines in the class are capable of delivering through either a deployed from the or the mounted on the dorsal side, although the latter was canceled in 2006 and removed from service in 2009. A variety of atmospheric control devices are used to allow the vessel to remain submerged for long periods of time without ventilating, including an, which produces oxygen for the crew and hydrogen as a byproduct.

The hydrogen is pumped overboard but there is always a risk of fire or explosion from this process. With an attachedWhile on the surface or at snorkel depth, the submarine may use the submarine's auxiliary or emergency for power or ventilation (e.g., following a fire).

The diesel engine in a 688 class can be quickly started by compressed air during emergencies or to evacuate noxious (non) gases from the boat, although 'ventilation' requires raising a snorkel mast. During nonemergency situations, design constraints call for operators to allow the engine to reach normal operating temperatures before it is capable of producing full power, a process that may take from 20 to 30 minutes. However, the diesel generator can be immediately loaded to 100% power output, despite design criteria cautions, at the discretion of the submarine commander on the recommendation of the submarine's engineer, if necessity dictates such actions to: (a) restore electrical power to the submarine, (b) prevent a reactor incident from occurring or escalating, or (c) to protect the lives of the crew or others as determined necessary by the commanding officer. Submerged at off the coast of, in July 2004 Propulsion The Los Angeles class is powered by the General Electric S6G. The hot reactor coolant water heats water in the steam generators, producing steam to power the propulsion turbines and ship's service turbogenerators (SSTGs), which generate the submarine's electrical power.

The high-speed propulsion turbines drive the shaft and propeller through a reduction gear. In the case of a reactor plant casualty, the submarine has a diesel generator and a bank of batteries to provide electrical power. An emergency propulsion motor on the shaft line or a retractable 325-hp secondary propulsion motor power the submarine off the battery or diesel generator.The S6G reactor plant was originally designed to use the D1G-2 core, similar to the D2G reactor used on the. The D1G-2 core had a rated thermal power of 150 MW and the turbines were rated at 30,000 shp. All Los Angeles-class submarines from on were built with a D2W core and older submarines with D1G-2 cores have been refueled with D2W cores.

The D2W core is rated at 165 MW and turbine power rose to approximately 33,500 shp. In popular culture. Los Angeles-class submarines have been featured prominently in numerous literary works and film adaptations, most notably in. Other appearances include in the novel and in. In addition to fictional works, Clancy's 1993 non-fiction book features an in-depth exploration of. was used in the 2008 made-for-television film., a 1989 submarine simulator, allowed the player to control a Los Angeles-class submarine during a set of missions.

After these submarines serve for 30 years, they could undergo a two-year overhaul and serve for one more 10-year operating cycle, for a total service life of 42 years.

An early submarine game with ten missions which can be played with both American and Soviet attack submarines. The game focuses on realism with several stations the player can use (sonar, weapons, navigation, helm, radio and periscope) but most duties can be delegated to crew members. The graphics are mostly close-up views of the control panels but in some occasions they feature digitized images of surface ships and crew.I can remember playing this game many years ago on the SEGA Megadrive (Genesis machine). I can't say i'm really a big fan of sub games or simulations in general but I found 688 attack sub to be a very playable and enjoyable game.The plot is simple fare, you are the captain of either an American or Soviet sub and must play through a series of increasingly difficult missions.

Graphics-wise the game was quite good for it's time, some of the fractal effects especialy were impressive. Those who like to tplay things at a slow, tactical pace will especialy like the game, and with many ways to complete each mission it's likely that you will through the game again when you finish it.Overall an enjoyable game, although maybe not one that will appeal to everyone.688 Attack Sub is a classic modern submarine simulation which puts you in command of either the American Los Angeles or the Soviet Alfa class nuclear-powered submarines. Most of the systems you would expect such as sonar and periscope are featured and nicely presented in VGA. The game offers ten missions for both the Soviet and American side in a Cold War scenario, that grows progressively hotter. Nice to see that the two sides' submarines have their own graphic sets in the game, even with some pseudo-cyrillic labels on the Russian side.Overall, 688 Attack Sub is an interesting early subsim and certainly a classic in the genre- arguably the best subsim for PC until Dynamix' Aces of The Deep years later. Especially the modem-play option was outstanding for its time. Be sure to download the manual, although the game is well laid-out and can be controlled completly with the mouse.Note: This is the full game and not the cut-down 'Maxell' version found on some abandonware sites.
