LCS: The USA’s Littoral Combat Ships

Exploit simplicity, numbers, the pace of technology development in electronics and robotics, and fast reconfiguration. That was the US Navy’s idea for the low-end backbone of its future surface combatant fleet. Inspired by successful experiments like Denmark’s Standard Flex ships, the US Navy’s $35+ billion “Littoral Combat Ship” program was intended to create a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes.

It hasn’t worked that way. In practice, the Navy hasn’t been able to reconcile what they wanted with the capabilities needed to perform primary naval missions, or with what could be delivered for the sums available. The LCS program has changed its fundamental acquisition plan 4 times since 2005, and canceled contracts with both competing teams during this period, without escaping any of its fundamental issues. Now, the program looks set to end early. This public-access FOCUS article offer a wealth of research material, alongside looks at the LCS program’s designs, industry teams procurement plans, military controversies, budgets and contracts.

SSGN “Tactical Trident” Subs: Special Forces and Super Strike

In the aftermath of the START-II arms control treaty, some of the USA’s nuclear-powered Ohio Class SSBN nuclear missile submarines were converted to become long range conventional strike and special operations SSGN “Tactical Tridents.” Four ultra-stealthy Ohio-class SSBNs had their 24 Trident II D-5 nuclear ballistic missiles removed. They were replaced with up to 154 Tomahawk cruise missiles, plus space in the sub for 66-102 special forces troops, special attachments for new Advanced SEAL Delivery System (ASDS) or older Seal Delivery Vehicle (SDV) “mini-subs,” and a mission control center. Unmanned Underwater Vehicles, and even UAVs for aerial operations, are expected to become equally important options over the SSGN fleet’s career.

These modifications provide the USA with an impressive and impressively flexible set of conventional firepower, in a survivable and virtually undetectable platform, which can remain on station for very long periods of time. As surveillance-strike complexes make the near-shore more and more hazardous for conventional ships, and the potential dangers posed by small groups continue to rise, America’s converted SSGN submarines will become more and more valuable. This updated, free-to-view article covers their origins and timeline, the key technologies involved, contracts from the program’s inception to the present day, with all 4 submarines back in service.

South Korea to Order 5 More U-214 AIP Submarines to Bridge to Indigenous Boats

Sohn Won-Yil & Nimitz

The German Type 214 was selected by Korea over the French/Spanish Scorpene Class that has been ordered by Chile, India, and Malaysia. Some would argue that U-214s are the most advanced diesel-electric submarines on the market, with an increased diving depth of over 400 meters, an optimized hull and propeller design, ultra-modern internal systems, and an Air Independent Propulsion (AIP) system that lets the diesel submarine stay submerged for long periods without needing to surface and snorkel air.

South Korea ordered its first 3 KSS-II/ Type 214 boats in 2000, which were assembled by Hyundai Heavy Industries. The Batch 2 order will add 6 more of the 65m, 1,700t boats, effectively doubling the ROKN’s number of modern submarines. The latest development is a $16 million order for Saab electronic systems for the 2nd batch of 214 submarines.

Gulf Chokepoint: Seafox Saves the Day?

Seafox Mk.II

Rising tensions in the Persian Gulf, coupling increasingly bellicose actions by Iran with pointed American warnings, have left international navies thinking hard about how to keep the Strait of Hormuz open for oil traffic. Naval mines, which can be laid by submarines or boats, remain one of the most difficult and inconvenient threats to counter. That was true during the last set of armed clashes between the USA and Iran in the 1980s. It remains true, and the USA has weakened its position by retiring its modern Osprey Class minehunter ships. Some are available for reactivation in an emergency, but their place was supposed to be taken by the MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system.

The USA is looking to bolster its defenses in the Straits, but AMCM isn’t quite ready yet. That leaves them looking elsewhere for urgent operational buys. While countries like China counter mines using unmanned ships, the US Navy is turning toward a widely-bought German UUV…

Underwater Gliders for the US Navy

Slocum Glider

Teledyne Brown Engineering, Inc., in Huntsville, AL recently received approval from the U.S. Navy to move into the Full Rate Production (FRP) Phase on the underwater Littoral Battlespace Sensing-Glider (LBS-G) Program. The first Full Rate Production option calls for the manufacture of 35 gliders, with additional options for 100 more, and a total contract value of $53.1 million if all options are exercised. US Space and Naval Warfare Systems Command manages the contract.

The Teledyne Team has already delivered 15 Low Rate Initial Production LBS-Gs to the US Navy’s Program Executive Office for C4I, under a December 2010 contract. That team includes Teledyne Brown (System Integration), Teledyne Webb Research in East Falmouth, MA (Slocum Glider development and production), and the University of Washington – Applied Physics Lab (Glider Operations Center software). Their 2m long design features a very innovative propulsion concept.

Up to $257.4M to APL-UW for Marine Research

RSN project concept

The Applied Physics Laboratories at the University of Washington in Seattle, WA received a $120.4 million cost-plus-fixed-fee, indefinite-delivery/ indefinite-quantity task order contract for up to 657,115 staff hours. Multiple appropriation types will be utilized throughout contract performance, and no funds are obligated by award of this contract, only on individual task orders. A contract option could bring the cumulative value of this contract to $257.4 million for up to 1,314,230 staff hours. Work will be performed in Seattle, WA, and is expected to be complete by April 2015. This contract was not competitively procured by the Naval Sea Systems Command in Washington Navy Yard, Washington, DC (N00024-10-D-6618).

The lab does a lot of civilian and military work, and even civilian programs like the Regional Scale Nodes Project ocean observatory would expand ocean access in ways that apply to both civilian and military systems. APL-UW will provide research, development, and engineering to US NAVSEA in 7 core competency areas that NAVSEA has deemed essential to support a variety of specific military programs. While this sort of work is less visible than buying a $700 million Littoral Combat Ship/ frigate, the combined effects of these efforts could be very significant in maintaining the US Navy’s future edge:

• Experimental oceanography
  
• Acoustic propagation
  
• Underwater instrumentation and equipment
  
• Marine corrosion
  
• Acoustic and related systems
  
• Simulations and signal processing; and
  
• Mission related research and development

Raytheon’s AN/AQS-20 Mine Detection Sonar (AMCM)

MH-60S w. AQS-20

Advances made in American mine detection technologies during the mid 2000s included the AQS-20A mine detecting sonar array and airborne laser systems mounted to MH-60S helicopters. All of this is in the service of the USA’s new naval emphasis on littoral warfare and accompanying doctrinal changes. So, what’s the AN/AQS-20? And how is it also related to a new US ship class, not to mention a new undersea robot?

Australia’s 2009 Defence White Paper

(click to download)

Defense was an issue in the 2007 Australian election. The center-left Labor Party attacked the center-right Liberal Party by citing mismanaged projects, and accusing the Howard government of making poor choices on key defense platforms like the F/A-18F Super Hornet and F-35A Joint Strike fighters. That sniping continued even after Labor won the election, and has been evident in more than a few Defence Ministry releases.

The new government made some program changes, such as canceling the SH-2G Seasprite contract. Yet it has been more notable for the programs it has not changed: problematic upgrades of Australia’s Oliver Hazard Perry frigates were continued, the late purchase of F/A-18F Super Hornets was ratified rather than canceled, and observers waited for the real shoe to drop: the government’s promised 2009 Defence White Paper, which would lay out Australia’s long-term strategic assessments, and procurement plans.

On May 2/09, Australia’s government released “Defending Australia in the Asia Pacific Century: Force 2030.” DID has reviewed that document, and the reaction to date including a new ASPI roundup of reactions from around Asia.

Legal Battles Over US Navy’s Marine Mammal Protection Measures

K-Dog: disco is worse

The global proliferation of advanced, ultra-quiet diesel electric submarines has prompted a number of responses around the globe, from initial-stage efforts to mimic a shark’s senses in the USA, to the most obvious route of using more powerful active sonars. In Western countries, concerns have been expressed that these sonars may disorient or scare marine mammals, leading to decompression sickness or disruption of their biological sonar navigation systems. This has led to (unsuccessful) lawsuits aimed at curtailing submarine exercises by Western navies.

In December 2007, USN Rear Adm. Lawrence S. Rice, director of Naval Operations Environmental Readiness, discussed some of the measures that are being taken to investigate the issue, and also mitigate any possible effects. In January 2008, a court battle erupted over undersea training off the coast of San Diego, CA, throwing the issue back into the limelight and potentially crippling Navy training before a dangerous deployment to the Persian Gulf. The 9th Circuit Court of Appeals’ follow-on ruling was predictable, but in November 2008, the US Supreme Court issued its ruling.

In light of that favorable ruling, a settlement has now been reached on the Navy’s terms. The Navy has just been given permission to conduct exercises near Hawaii, and this, too, is likely to end up in court, along with its planned training near Florida. Meanwhile, the US Navy continues to fund marine mammal research – which may begin to include UUVs and/or USVs…

SWARMS Project: Swarming Drones to Sting the Enemy?

UAV Swarm
(click to view larger)

Like a swarm of angry bees, unmanned aerial, ground, and sea vehicles automonously converge on enemy troops, aircraft and ships, decide what to do, then engage the enemy with surveillance or weapons to help U.S. forces defeat them. All this without direct human intervention. Sounds like science fiction? The American military is one of several working on the technology, called “swarming,” in order to make this scenario a reality.

According to the SWARMS project at the University of Pennsylvania, future military missions will rely on large, networked groups of small unmanned vehicles and sensors. Groups of this type will typically operate with little or no direct human supervision most of the time. It will be very difficult, if not impossible, to guarantee individual management or control in the kind of dynamic, resource-constrained, adversarial environments that characterize human warfare. Managing such large groups will thus be extremely challenging, and will require the application of new, yet-to-be-developed methods of communication, control, computation and sensing, specifically tailored to the command and control of large-scale, autonomous vehicle groups.
