The USA’s E-6 Fleet: Take Charge, And Move Out!

Mar 21, 2023 04:58 UTC DII

Latest updates[?]: Northrop Grumman has submitted a bid for the US Navy’s E-6B Mercury command, control, and communications aircraft replacement program. The US defense giant is offering its “weapons system integration and battle management leadership” for the E-6 recapitalization aircraft (E-XX) Take Charge And Move Out (TACAMO) program. The aircraft will be based on the C-130J platform.  “Our extensive experience integrating aircraft and mission systems, combined with our expertise in creating operationally-ready solutions in support of the nuclear enterprise, makes Northrop Grumman the optimal partner to deliver the Navy’s E-XX TACAMO weapon system,” Northrop vice president Janice Zilch said.

E-6B TACAMO

The USA’s E-6 Mercury (aka. TACAMO, as in TAke Charge And Move Out) “survivable airborne communication system” airplanes support their Navy’s SSBN ballistic missile submarine force and overall strategic forces. With the advent of the new “Tactical Trident” converted Ohio Class special operations subs, their unique capabilities become even more useful. The E-6B version also has a secondary role as a “Looking Glass” Airborne National Command Post, and in recent years they have seen use as communications relay stations over the front lines of combat.

Delivery of the first production E-6 aircraft took place in August 1989, with delivery of the 16th and final airplane coming in May 1992. This is DID’s FOCUS Article concerning the E-6 system, which includes details concerning the capabilities and associated contracts. The latest contracts involve important fleet upgrades, as the Navy tries to drag the jet’s systems into the 21st century.

Airfields Afloat: The USA’s New Gerald Ford Class Super-Carriers

Mar 20, 2023 04:56 UTC DII

Latest updates[?]: Huntington-Ingalls Industries won a $16 million modification for the procurement of material and labor associated with contractor furnished On-Board Repair Parts (OBRP) for the outfitting of CVN 79. Work will be performed in Newport News, Virginia, and is expected to be completed by June 2024.

CV-74 USS Stennis and CV HMS Illustrious

USA’s Nimitz Class &
UK’s Invincible Class

Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.

As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.

DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.

LPD-17 San Antonio Class: The USA’s New Amphibious Ships

Mar 17, 2023 04:58 UTC DII

Latest updates[?]: General Dynamics won a $9 million modification to exercise options on previously awarded contract N00024-23-C-4413 for the USS Arlington (LPD 24) fiscal 2023 docking selected restricted availability. Work will be performed in Norfolk, Virginia, and is expected to be completed by September 2024. Mid-Atlantic Regional Maintenance Center (MARMC), Norfolk, Virginia, is the contracting activity. The USS Arlington is a a San Antonio-class amphibious transport dock.

LPD-17 cutaway

LPD-17 San Antonio class amphibious assault support vessels are just entering service with the US Navy, and 11 ships of this class are eventually slated to replace up to 41 previous ships. Much like their smaller predecessors, their mission is to embark, transport, land, and support elements of a US Marine Corps Landing Force. The difference is found in these ships’ size, their cost, and the capabilities and technologies used to perform those missions. Among other additions, this new ship is designed to operate the Marines’ new MV-22 Osprey tilt-rotor aircraft, alongside the standard well decks for hovercraft and amphibious armored personnel carriers.

While its design incorporates notable advances, the number of serious issues encountered in this ship class have been much higher than usual, and more extensive. The New Orleans shipyard to which most of this contract was assigned appears to be part of the problem. Initial ships have been criticized, often, for sub-standard workmanship, and it took 2 1/2 years after the initial ship of class was delivered before any of them could be sent on an operational cruise. Whereupon the USS San Antonio promptly found itself laid up Bahrain, due to oil leaks. It hasn’t been the only ship of its class hurt by serious mechanical issues. Meanwhile, costs are almost twice the originally promised amounts, reaching over $1.6 billion per ship – 2 to 3 times as much as many foreign LPDs like the Rotterdam Class, and more than 10 times as much as Singapore’s 6,600 ton Endurance Class LPD. This article covers the LPD-17 San Antonio Class program, including its technologies, its problems, and ongoing contracts and events.

Serious Dollars for AEGIS Ballistic Missile Defense (BMD)

Mar 15, 2023 04:58 UTC DII

Latest updates[?]: Lockheed Martin Rotary and Mission Systems won a $48.5 million modification for AEGIS fielding and sustainment engineering support, software development, in-service maintenance, integration, and logistics and fielding support for AEGIS combat system configurations already delivered, or in the process of being delivered, to the Navy fleet. Work will be performed in Moorestown, New Jersey (96%); and Dahlgren, Virginia, and is expected to be completed by December 2023.

The AEGIS Ballistic Missile Defense System seamlessly integrates the SPY-1 radar, the MK 41 Vertical Launching System for missiles, the SM-3 Standard missile, and the ship’s command and control system, in order to give ships the ability to defend against enemy ballistic missiles. Like its less-capable AEGIS counterpart, AEGIS BMD can also work with other radars on land and sea via Cooperative Engagement Capability (CEC). That lets it receive cues from other platforms and provide information to them, in order to create a more detailed battle picture than any one radar could produce alone.

AEGIS has become a widely-deployed top-tier air defense system, with customers in the USA, Australia, Japan, South Korea, Norway, and Spain. In a dawning age of rogue states and proliferation of mass-destruction weapons, the US Navy is being pushed toward a “shield of the nation” role as the USA’s most flexible and most numerous option for missile defense. AEGIS BMD modifications are the keystone of that effort – in the USA, and beyond.

The USA’s DDG-1000 Zumwalt Class Program: Dead Aim, Or Dead End?

Feb 22, 2023 04:58 UTC DII

Latest updates[?]: The US Navy awarded Gibbs & Cox a $39.6 million future surface combatant force (LSCF) design and engineering contract. The contract, through February 2024, supports the next-generation guided-missile destroyer (DDG(X))and other emerging ship concepts. It also includes feasibility studies in support of the broader navy fleet.

DDG-1000 2 Ships Firing Concept

67% of the fleet

DID’s FOCUS Article for the DDG-1000 Zumwalt Class “destroyer” program covers the new ships’ capabilities and technologies, key controversies, associated contracts and costs, and related background resources.

The ship’s prime missions are to provide naval gunfire support, and next-generation air defense, in near-shore areas where other large ships hesitate to tread. There has even been talk of using it as an anchor for action groups of stealthy Littoral Combat Ships and submarines, owing to its design for very low radar, infrared, and acoustic signatures. The estimated 14,500t (battlecruiser size) Zumwalt Class will be fully multi-role, however, with undersea warfare, anti-ship, and long-range attack roles. That makes the DDG-1000 suitable for another role – as a “hidden ace card,” using its overall stealth to create uncertainty for enemy forces.

Zumwalt parody

True, or False?

At over $3 billion per ship for construction alone, however, the program faced significant obstacles if it wanted to avoid fulfilling former Secretary of the Navy Donald Winter’s fears for the fleet. From the outset, DID has noted that the Zumwalt Class might face the same fate as the ultra-sophisticated, ultra-expensive SSN-21 Seawolf Class submarines. That appears to have come true, with news of the program’s truncation to just 3 ships. Meanwhile, production continues.

Trident II D5 Missile: Keeping Up with Changing Times

Feb 20, 2023 04:58 UTC DII

Latest updates[?]: The Charles Stark won a $95.1 million modification, which exercises fiscal 2023 options to provide technical and engineering services necessary to maintain and sustain the Trident II Strategic Weapon System MK 6 Guidance subsystem. The effort also includes a requirement for strategic guidance, navigation, and control subject matter expertise and resources to plan and implement an advanced development program that explores and evaluates current and maturing concepts and technologies that will enable follow-on, full-scale development of the second life extension of the Navy’s Trident II Strategic Weapons Systems. Work will be performed in Cambridge, Massachusetts (81%); and El Segundo, California (19%), and is expected to be completed September 30, 2024.

Trident II D-5 Test Launch

Trident II D5 Test Launch

Nuclear tipped missiles were first deployed on board US submarines at the height of the Cold War in the 1960s, to deter a Soviet first strike. The deterrence theorists argued that, unlike their land-based cousins, submarine-based nuclear weapons couldn’t be taken out by a surprise first strike, because the submarines were nearly impossible to locate and target. Which meant that Soviet leaders could not hope to destroy all of America’s nuclear weapons before they could be launched against Soviet territory. SLBM/FBM (Submarine Launched Ballistic Missile/ Fleet Ballistic Missile) offered shorter ranges and less accuracy than their land-based ICBM (Inter-Continental Ballistic Missile) counterparts, but the advent of Trident C4 missiles began extending those ranges, and offering other improvements. The C4s were succeeded by larger Trident II D5 missiles, which added precision accuracy and more payload.

The year that the Trident II D5 ballistic missile was first deployed, 1990, saw the beginning of the end of the missile’s primary mission. Even as the Soviet Union began to implode, the D5’s performance improvements were making the Trident submarine force the new backbone of the USA’s nuclear deterrent – and of Britain’s as well. To ensure that this capability was maintained at peak readiness and safety, the US Navy undertook a program in 2002 to replace aging components of the Trident II D5 missile called the D5 Life Extension (LE) Program. This article covers D5 LE, as well as support and production contracts associated with the American and British Trident missile fleets.

SSBN-X Subs: Congressmen Promote Refresh, Have Sub Bases in Districts

Jan 20, 2023 04:58 UTC

Latest updates[?]: BAE Systems won a $72 million deal for the manufacture and delivery of five Columbia-class submarine components. Work will be performed in Louisville, Kentucky (100%), and is expected to be completed by May 2030. Fiscal 2023 National Sea-Based Deterrence Fund funds in the full amount will be obligated at time of award, of which none will expire at the end of the current fiscal year. The Columbia-class program's goal is to design and build a class of 12 new ballistic missile submarines SSBNs to replace the Navy’s current force of 14 aging Ohio-class SSBNs. The Ohio-class submarines were designed to have a service life of 42 years (two 20-year cycles with a 2-year midlife nuclear refueling period). As the Ohio-class SSBNs were first deployed in 1981, they will start reaching the end of their service between 2027 and 2040, at a rate of about one boat per year. Starting in 2031, the Navy plans to replace each retiring Ohio-class boat with a new Columbia-class SSBN submarine.

Early SSBN-X Concept

SSBN-X concept

The US Navy needs new SSBN nuclear missile submarines. Their existing Ohio Class boats will begin to retire at a rate of 1 hull per year, beginning in 2027, as they reach the end of their 42-year operational lifetimes. Hence SSBN-X, also known as the Ohio Replacement Program for now.

The first step toward recapitalization involved a new Common Missile Compartment and Advanced Launcher for current and future nuclear missiles. The next step involves finalizing a design that can serve effectively to 2080, without destroying the US Navy’s shipbuilding budget in the process. Good luck with that one, but they have to to try. The maintenance of the USA’s nuclear deterrent is too important, in a world where nuclear weapons are proliferating.

Adding Arleigh Burkes: H.I.I. Steps Forward for DDG-51 Restart

Jan 19, 2023 04:58 UTC

Latest updates[?]: The US Navy has awarded BAE Systems a $119.2-million contract to revamp the USS Lassen (DDG 82) Arleigh Burke Class guided-missile destroyer. As part of the depot maintenance period (DMP) agreement, the company will upgrade the ship’s command and control platform, refurbish its crew cabin and engineering stations, and preserve its underwater hull. BAE Systems will dry-dock the ship at its Jacksonville Ship Repair facility in Florida for seven months, while the overall repairs will run until April 2024.

DDG-110

DDG-110 Construction

In April 2009 Bath and Ingalls agreed to the Navy’s surface combatant plans, thus heralding a significant restructuring within the American naval shipbuilding community. Under the agreements, the USA would end production at 3 Graf Spee sized DDG-1000 Zumwalt Class “destroyers,” but shift all production from the Congressionally-mandated joint arrangements to General Dynamics Bath Iron Works in Maine, which had already made program-related investments in advanced shipbuilding technologies.

Northrop Grumman (now Huntington Ingalls Industries) would retain its DDG-1000 deckhouse work, but their main exchange was additional orders for DDG-51 Arleigh Burke Class destroyers. Their Ingalls yard in Pascagoula, Mississippi would continue building the DDG-51 destroyers, beginning with 2 ordered in FY 2010-2011.

Virginia Block III: The Revised Bow

Dec 09, 2022 04:58 UTC

Latest updates[?]: Austal USA and General Dynamics Electric Boat (GDEB) have partnered on production work to support the US Navy’s Virginia-class and future Columbia-class nuclear-powered submarine fleet at Mobile, Alabama. As part of the collaboration, Austal will develop and integrate electronic deck modules and command and control systems for both submarine classes. Work on the sub-surface components is being conducted at Austal’s facility in Mobile, Alabama.

“GDEB Receives $148M as Virginia Class Lead Yard” described changes to the Virginia Class submarine’s design that are expected to reach 20% of the $200 million savings goal by the time orders for the versatile sea attack/ land attack/ special forces submarines rise to 2 per year, in 2012.

The bow changes cover the FY 2009-2013 ships, referred to as Block III. SSN 774 Virginia – SSN 777 North Carolina are Block I, and SSNs 778-783 will be Block II. Block III begins with the 11th ship of class, SSN 784. Long lead time component orders began May 22/08, and the submarine is expected to be ready for delivery around 2015. A fuller explanation of Block III’s extensive bow changes, and an accompanying graphic, may be found below – along with contract updates that include additional improvements and sonar development.

Phalanx CIWS: The Last Defense, On Ship and Ashore

Dec 08, 2022 04:58 UTC DII

Latest updates[?]: Raytheon won a $59.3 million by the US Navy for the Phalanx Close-In Weapon System (CIWS), SeaRAM, and Land-based Phalanx Weapon System. Work will be performed in Arizona, California, Mississippi, Texas and New Jersey and is expected to be completed by January 2024.

Phalanx CIWS Firing

Phalanx, firing

The radar-guided, rapid-firing MK 15 Phalanx Close-In Weapons System (CIWS, pron. “see-whiz”) can fire between 3,000-4,500 20mm cannon rounds per minute, either autonomously or under manual command, as a last-ditch defense against incoming missiles and other targets. Phalanx uses closed-loop spotting with advanced radar and computer technology to locate, identify and direct a stream of armor piercing projectiles toward the target. These capabilities have made the Phalanx CIWS a critical bolt-on sub-system for naval vessels around the world, and led to the C-RAM/Centurion, a land-based system designed to defend against incoming artillery and mortars.

This DID Spotlight article offers updated, in-depth coverage that describes ongoing deployment and research projects within the Phalanx family of weapons, the new land-based system’s new technologies and roles, and international contracts from FY 2005 onward. As of Feb 28/07, more than 895 Phalanx systems had been built and deployed in the navies of 22 nations.
