The USA’s America Class NAAS: Carrier Air + Amphibious Assault

Latest updates: LHA 7 wil be USS Tripoli, continuing a tradition.

LHA-R
LHA-R/NAAS Concept

Modern U.S. Navy Amphibious Assault Ships project power and maintain presence by serving as the cornerstone of the Amphibious Readiness Group (ARG) / Expeditionary Strike Group (ESG). LHA/LHD are a key element of the Seapower 21 doctrine pillars of Sea Strike and Sea Basing, transporting, launching, and landing elements of the Marine Expeditionary Brigade (MEB) via a combination of LCAC hovercraft, amphibious transports and vehicles, helicopters, and aircraft.

Designed to project power and maintain presence, LHA-Replacement (LHA-R, aka. LH-X, and now the New Amphibious Assault Ship) large deck amphibious assault ships were slated to replace the US Navy’s 6 LHA-1 Tarawa Class vessels. They are based on the more modern LHD Wasp Class design, with the LHD’s landing craft and well deck removed in favor of more planes and hangar space. While its LHA/LHD predecessors were amphibious assault ships with a secondary aviation element, it’s fair to describe the America Class as escort carriers with a secondary amphibious assault role.

Arming RQ-7 UAVs: The Shadow Knows…

RQ-7 Shadow

By 2007, US Army RQ-7 Shadow battalion-level UAVs had seen their flight hours increase to up 8,000 per month in Iraq, a total that compared well to the famous MQ-1 Predator. Those trends have gained strength, as workarounds for the airspace management issues that hindered early deployments become more routine. Some RQ-7s are even being used to extend high-bandwidth communications on the front lines.

The difference between the Army’s RQ-7 Shadow UAVs and their brethren like the USAF’s MQ-1A Predator, or the Army’s new MQ-1C Sky Warriors, is that the Shadow has been too small and light to be armed. With ultra-small missiles still in development, and missions in Afghanistan occurring beyond artillery support range, arming the Army’s Shadow UAVs has become an even more important objective. It would take some new technology, but that seems to be on the way for the US Army’s RQ-7B Shadow UAV fleet:

Rapid Fire May 3, 2012: Developmental Test Report

  • Chinese Rear Adm. Zhang Zhaozhong said that Zumwalt ships are vulnerable to being zerged. Well, he didn’t make an actual reference to videogame swarming aliens, but that’s the gist of his position.

Klubs No-Trump: the USA’s MSST Supersonic Target

MSST Concept, ATK
MSST concept

In order to defend against a threat, you have to be able to simulate it for realistic training and evaluation. Navy ships are increasingly threatened by supersonic anti-ship missiles, which can leave defenders as little as 45 seconds from the moment they break the horizon to impact with the ship. The USA’s GQM-163 Coyote target was developed to simulate those, but the Russians also sell an interesting hybrid threat. The 3M54E “SS-N-27 Sizzler” variant of the Klub missile uses the usual sub-sonic, sea-skimming approach in order to extend its range, until it gets within 60 km/ 36 miles of its target. Then it boosts to supersonic speed, and performs evasive maneuvers to confuse defenses.

It’s a deadly threat. Which is why the USA has been funding the Multi-Stage Supersonic Target Program since 2008, in order to develop a target that can bring the same kind of sizzle to defensive exercises.

Listening Sticks: US Navy Sonobuoy Contracts

Latest updates: Active sonobuoy order; Sparton sub-contracts.

P-8A Dropping Sonobuoy Concept
P-8A: Sonobuoy drop

Sonobuoys are used to detect and identify moving underwater objects by either listening for the sounds produced by propellers and machinery (passive detection), or by bouncing a sonar “ping” off the surface of a submarine (active detection). They usually float, or have at least some part of them that does. Specialized sonobuoys can also detect electric fields, magnetic anomalies, and bioluminescence (light emitted by microscopic organisms disturbed by a passing submarine); as well as measuring environmental parameters like water temperature versus depth, air temperature, barometric pressure, and wave height.

Sonobuoys are generally dropped from aircraft or helicopters that are equipped with a means to launch them, and electronic equipment to receive and process data sent by the sonobuoy. They can also be launched from ships. This entry will discuss some of the new sonobuoys in use, and cover related contracts:

USA Developing New 3DELRR Long-Range Ground Radar

Latest updates: Big shift in budgets & acquisition strategy – full details inside.
AN/TPS-75
AN/TPS-75

The US Air Force’s AN/TPS-75 radar has been in service since 1968. Threats have evolved, and they want to replace it as its main long-range, ground-based radar for detecting, identifying and tracking aircraft and missiles, then reporting them through the Ground Theater Air Control System. The US Marines are considering a similar move, to replace their own AN/TPS-59s. Hence the USA’s Three-Dimensional Expeditionary Long-Range Radar (3DELRR).

3DELRR is intended to provide long-range surveillance, control of aircraft, and theater ballistic missile detection. It will correct AN/TPS-75 shortfalls by being easier to maintain, thanks to AESA technology, and by detecting and reporting highly maneuverable and/or stealthy targets. Its improved resolution may even allow it to classify and determine the type of non-cooperative aircraft that cannot or do not identify themselves – a trait that allows faster engagement of hostile planes, and reduces the odds of friendly fire incidents. As long as the program itself can avoid friendly fire from the USA’s budget wars:

MOPping Up: The USA’s 30,000 Pound Bomb

Latest updates: Here’s $100M, make it badder.
Grand Slam Bomb
“Grand Slam”

During the Second World War, attacking heavily protected targets like U-boat pens and protected “V-weapon” facilities was a key challenge. Enter a brilliant British engineer named Barnes Wallis, fresh off the dam-busting “Upkeep” bouncing bomb. His next trick was a 12,000 pound weapon called the “Tallboy,” a streamlined, spin-stabilized bomb with a claimed terminal velocity of Mach 1 when dropped from 20,000 feet. That mass, carrying 5,200 pounds of Torpex D1 explosive, made a crater 80 feet deep x 100 feet across when it hit. By 1945, Wallis’ next “Earthquake bomb” was in production – the 22,000 pound “Grand Slam.” His creations made short work of U-boat pens.

These bombs went out of fashion with the advent of nuclear weapons, but if you wait long enough, fashion comes around again. Enter the USA’s new Massive Ordnance Penetrator (MOP). Despite additional funding, and October promises of accelerated deployment, the MOP did not arrive by mid-2010, as planned. Development continues, however, and fielding draws closer:

AGM-88E AARGM Missile: No Place To Hide Down There

Latest updates: Testing & program reports highlight problems, schedule; Contract for Block I fixes.

AGM-88E AARGM Launch Concept
AARGM Concept

The AGM-88E Advanced Anti-Radiation Guided Missile (AARGM) is a medium range, supersonic, air-launched tactical missile whose primary job is to attack and kill enemy radars. AARGM is a US Navy major acquisition program, with around 1,750 expected orders from the U.S. Navy and Marine Corps. The Italian Air Force is expected to buy up to 250 of these successors to the AGM-88 High-Speed Anti-Radiation Missile, and Germany may also join.

So, why is AARGM a big deal? Perhaps the story of how a Serbian unit using an antiquated SA-3 battery managed to survive the 1999 NATO air campaign – and shoot down an F-117 Nighthawk stealth plane – will help put things into perspective. DID recounts those events, explains the new weapon, and offers updates on contracts and key milestones.

LCS & MH-60S Mine Counter-Measures Continue Development

Latest updates: ALMDS production order.

MH-53E/Mk-105
Old school:
MH-53E & Mk-105 sled

The US Navy currently uses large CH-53/MH-53 helicopters and towed sleds to help with mine clearance work, but they hope to replace those old systems with something smaller and newer. The MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system adds an operator’s station to the helicopter cabin, additional internal fuel stores, and towing capability, accompanied by a suite of carried systems that can be mixed and matched. AMCM is actually 5 different air, surface and sub-surface mine countermeasures systems, all deployed and integrated together in the helicopter.

While the US Navy develops AMCM, and complementary ship-launched systems for use on the new Littoral Combat Ships, new minehunter ship classes like the Ospreys are being retired by the US Navy and sold. All in an era where the threat of mines is arguably rising, along with tensions around key chokepoints like the Suez Canal and Strait of Hormuz.

This article explains the components involved (AQS-20, ALMDS, AMNS, OASIS, RAMICS; COBRA, RMS, SMCM), chronicles their progress through reports and contracts, and provides additional links for research.

JLTV: Hummer v2.0, or MRAP Lite?

Latest updates: Bids in for JLTV; US military confident – is that justified?; Navistar & BAE split, and AM General has a separate bid from GDLS.

Ultra APV
Ultra APV demonstrator

In an age of non-linear warfare, where front lines are nebulous at best and non-existent at worst, one of the biggest casualties is… the concept of unprotected rear echelon vehicles, designed with the idea that they’d never see serious combat. That imperative is being driven home on 2 fronts. One front is operational. The other front is buying trends.

These trends, and their design imperatives, found their way into the USA’s Joint Light Tactical Vehicle (JLTV) program, which aims to replace many of the US military’s 120,000 or so Humvees. The US military’s goal is a 7-10 ton vehicle that’s lighter than its MRAPs and easier to transport aboard ship, while offering substantially better protection ad durability than existing up-armored Humvees. They’d also like a vehicle that can address front-line issues like power generation, in order to recharge all of the batteries troops require for electronic gadgets like night sights, GPS devices, etc.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. JLTV certainly qualifies, and recent budget planning endorsements have solidifed a future that was looking shaky. Now, can the Army’s program deliver?
