The VOSS I features commercial off-the-shelf components, high-resolution color and infrared sensors, night vision and laser rangefinder capabilities in a 15-inch/38-cm turret. Working together, the U.S. Navy and Lockheed Martin quickly identified a VOSS I from the U.S. Government’s existing inventory and completed the installation on USNS Grapple (T-ARS-53) within two weeks.

«To support NATO’s security mission quickly, the U.S. Navy needed long-range detection and identification capabilities to identify ships and small water craft», said Paul Lemmo, vice president of Fire Control/ Special Operations Forces Contractor Logistics Support Services (SOF CLSS) at Lockheed Martin Missiles and Fire Control. «Because of its proven performance in theater, durability and universal mount design, VOSS I was the ideal solution to delivering the U.S. Navy a quick reaction capability».

VOSS I is designed with solid, weather-tight construction and universal mounts that allow it to easily move from a ground vehicle to a maritime vessel. Combat-proven in extreme environments (camera systems uphold full functionality in temperatures from -25° to +135° Fahrenheit/-32° to +57° Celsius; they also operate smoothly despite harsh environmental stresses of sand, dust, mud, rain, snow and fog), more than 1,100 VOSS systems have been deployed with the U.S. Army, U.S. Marine Corps, NATO and law enforcement agencies across multiple platforms.

Symphony – the jammer

In today’s rapidly changing battlespace, our adversaries are using technology to their advantage to turn the most commonplace devices into explosives. The U.S. Navy recently approved Symphony Block 40, Lockheed Martin’s counter-Improvised Explosive Device (IED) system, which provides enhanced capabilities that allow partner nations to combat ever-changing threats.

Symphony Block 40 is an open architecture system developed with the latest technologies to address new and emerging threats. This system simultaneously jams select or multiple electronic signals used to trigger a Radio-Controlled (RC) IED. The jammer is a small, vehicle-mounted system with an open architecture design that provides continuous coverage across the entire threat spectrum, as well as includes updated capabilities for maximum effectiveness, security, and response.

«Symphony Block 40 builds on the proven performance and 10 years of experience protecting warfighters. The system’s enhanced capabilities will give men and women in uniform the latest technology to counter rapidly evolving threats so they can complete their missions», said Joe Ottaviano, Director, Electronic Warfare (EW), Lockheed Martin.

The United States and its allies rely on Symphony to protect warfighters in an unpredictable future. The Symphony product line is the only counter-IED systems of its kind approved by the U.S. government for foreign military sale to allied, coalition and partner nations.

More than 4,500 Symphony Block 10/20 variant systems currently support U.S. and coalition forces in Iraq, Afghanistan, and other areas of conflict.

Work on the Symphony line of products is done in Clearwater, Florida, Manassas, Virginia, and Syracuse, New York, under an Indefinite Delivery Indefinite Quantity (IDIQ) contract with the U.S. Navy.

Lockheed Martin provides global electronic warfare solutions through a unique open architecture product platform and open business model. In the air, on land, and at sea, Lockheed Martin pioneers advanced technologies to control the electromagnetic spectrum, and develops disruptive technologies to outpace adversary threats. The key to success lies not only in the capability of the systems, but integration of those systems across platforms to offer a complete picture of the battle space and unimpeded use of the electromagnetic spectrum for the warfighter.

The joint Sikorsky/Naval Air Systems Command (NAVAIR) VH-92A helicopter program team met in July with key collaborators from government and industry for an in-depth design review.

Throughout the review the VH-92A program team successfully demonstrated that the design meets the system requirements. Review participants included NAVAIR and industrial partners who took part in the technical presentations.

«This milestone is an important achievement for our program and demonstrates Sikorsky and NAVAIR are well aligned», said Spencer Elani, Sikorsky director, VH-92A helicopter program. «We got here by completing several milestones on or ahead of schedule. We are committed to staying on that track as we head into the building phase of the program».

The U.S. Navy awarded a $1.24 billion fixed-price incentive Engineering and Manufacturing Development (EMD) contract with production options to Sikorsky on May 7, 2014, for 21 operational and two test aircraft.

Initial fielding is planned for 2020, with production concluding in 2023. Under the contract, Sikorsky will use its production S-92 aircraft and integrate government defined mission systems and an executive interior.

«This is an important step forward in the replacement of our presidential fleet of helicopters. The successful CDR demonstrates this helicopter system meets the requirements of the USMC and gives them exceptional mission performance from a platform that is affordable and supportable for this important mission», said U.S. Marine Corps Colonel Robert Pridgen, program manager for the Naval Air System Command’s Presidential Helicopter’s Program Office.

Two Engineering Development Model (EDM) aircraft are undergoing the modification process at Sikorsky’s Stratford, Conn., location. First flight of a VH-92A configured aircraft is planned for 2017.

The VH-92A will transport the president and vice president of the United States and other officials. Sikorsky brings unmatched experience and a proven track record to this mission having flown every US commander-in-chief since President Dwight D. Eisenhower. The VH-92A will continue this legacy for decades to come.

Test at RIMPAC

Littoral combat ship USS Coronado (LCS-4) successfully executed the first live-fire over-the-horizon missile test using a Harpoon Block IC missile, July 19, during the Navy’s Rim of the Pacific (RIMPAC) exercise.

The test event validated the operation of the Harpoon missile aboard a littoral combat ship and provided the necessary engineering data to support future ship upgrades.

«This Harpoon demonstration on USS Coronado supports the Navy’s larger distributed lethality concept to strengthen naval power at and from the sea to ensure the Navy maintains its maritime superiority», said Rear Admiral Jon Hill, program executive officer for Integrated Warfare Systems (PEO IWS).

The Harpoon installation aboard Coronado involved the collaboration of fleet and industry partners, such as ship designers, system design and sustainment experts, and installers to rapidly adapt and install the missile on Coronado.

«The incorporation of an ‘off-the-shelf’ Harpoon missile on USS Coronado in less than four months was no small feat and supports the Chief of Naval Operations’ focus on accelerated learning to bring capabilities to the fleet faster», said Captain Joe Mauser, PEO IWS Harpoon lead.

Harpoon is an all-weather, over-the-horizon weapon designed to execute anti-ship missions against a range of surface targets. It can be launched from surface ships, submarines and aircraft and is currently used on 50 U.S. Navy ships: 22 cruisers, 21 Flight I destroyers and seven Flight II destroyers.

The test is part of a greater strategy by the Navy to increase the lethality and survivability of littoral combat ships, which includes demonstrating and deploying over-the-horizon capability on Coronado and USS Freedom (LCS-1) in the near term.

«With every deployment, LCS is bringing increased capability to the fleet, and USS Coronado is no exception», said Rear Admiral John Neagley, program executive officer for LCS. «The Harpoon demo is yet another example of the power and promise of these warships».

In September 2015, Director of Surface Warfare Rear Adm. Peter Fanta directed the installation of a technologically mature, over-the-horizon capability across in-service littoral combat ships to support the Navy’s distributed lethality concept. Priority was given to Coronado and Freedom as ships preparing to deploy in fiscal year 2016.

In the case of Coronado, an in-service variant of the Harpoon Weapon System (HSLCLS 9/10 and Block 1C missile) was selected as a proven off-the-shelf combat capability.

While this demo represents the first over-the-horizon Harpoon test from an Independence-variant LCS in an operational setting, no decision has been made on which over-the-horizon missile will be integrated into the LCS platform. That will be determined by a future competitive contract award.

RIMPAC is a biennial multinational exercise that provides a unique training opportunity that fosters sustained cooperative relationships critical to ensuring the safety of sea lanes and security on the world’s oceans.

Terrex IFV family

According to Kelvin Wong, IHS Jane’s International Defence Review correspondent, Singapore Technologies (ST) Kinetics, the land systems division of state-affiliated defence prime ST Engineering, is seeking to expand its global 8×8 armoured vehicle footprint with the Terrex family of Infantry Fighting Vehicles (IFVs), which now includes three distinct platforms with Gross Vehicle Weight (GVW) ratings ranging from 24-35 tonnes.

All three members of the ST Kinetics 8×8 Terrex armoured vehicle family pictured together for the very first time. From left: the 24-tonne Terrex 1 which is in service with the Singapore Army; the 35-tonne Australian Land 400 Phase 2 contender Terrex 3/Sentinel II; and the 30-tonne Terrex 2 that has been optimised for amphibious operations, one of the two finalists downselected for the US Marine Corps ACV 1.1 programme

Senior ST Kinetics executives asserted during a closed press briefing on 22 July – which also commemorated an occasion where all three current members of the Terrex family were displayed together for the first time – that the company’s sustained efforts in capability development will enable it to meet the growing spectrum of operational requirements from international customers.

Winston Toh, ST Kinetics executive vice-president and chief marketing officer, told that the company’s 8×8 vehicles have also garnered interest from countries in the Middle East as well as North and South America, in addition to the Australian Army Project Land 400 Phase 2 and US Marine Corps (USMC) Amphibious Combat Vehicle Phase 1 Increment 1 (ACV 1.1) programmes that it is currently pursuing with overseas industry partners.

«We have adopted different business models to cater to the customers’ needs», Toh explained. «For example, we are the vehicle OEM but we are providing our partners with design and engineering capabilities to support in-country manufacturing … which helps manage cost and risk for the customer».

Toh admitted that while Terrex has yet to make inroads in the Asia Pacific region outside of Singapore, ST Kinetics has leveraged on its experience with Terrex to provide technical advice and consultancy services to Thailand’s Defence Technical Institute’s (DTI’s) indigenous 24-tonne 8×8 Black Widow Spider armoured vehicle development for the Royal Thai Army (RTA).

The acceptance trial is the last significant milestone before delivery of the ship to the Navy, which is planned for this fall. During the trial, the Navy conducted comprehensive tests of the Littoral Combat Ship (LCS) intended to demonstrate the performance of the propulsion plant, shiphandling and auxiliary systems. While underway, the ship successfully performed launch and recovery operations of the 36-foot/11-meter Rigid Hull Inflatable Boat (RHIB), conducted surface and air self-defense detect-to-engage exercises, and demonstrated the ship’s maneuverability.

«Another thorough trial by the Board of Inspection and Survey, and another ship with improved scores and at a lower cost than her predecessor», said LCS Program Manager Captain Tom Anderson. «Detroit’s performance during acceptance trial is a testament to the hard work of the Marinette workforce. I look forward to placing the ship in the capable hands of her crew later this summer».

Following delivery and commissioning in its namesake city of Detroit, LCS-7 will sail to California to be homeported in San Diego with sister ships USS Freedom (LCS-1), USS Fort Worth (LCS-3) and USS Milwaukee (LCS-5).

Several more Freedom variants are under construction at Fincantieri Marinette Marine Corporation in Marinette, Wisconsin. Future USS Little Rock (LCS-9) is preparing for builder’s trials. Christened in January, future USS Sioux City (LCS-11) is currently conducting system testing in preparation for trials in 2017. Future USS Wichita (LCS-13) is preparing for launch in the fall. Meanwhile future USS Billings (LCS-15) laid her keel in November 2015 and sister ship future USS Indianapolis (LCS-17) started fabrication in August 2015 and laid her keel in July. Additional ships in the pre-production phase include future USS St. Louis (LCS-19), future USS Minneapolis/St. Paul (LCS-21), future USS Cooperstown (LCS-23) and to-be-named future LCS-25.

Designed and built by two industry teams, the LCS class consists of the Freedom variant led by Lockheed Martin, and the Independence variant led by Austal USA for USS Jackson (LCS-6) and follow-on even-numbered hulls; General Dynamics Bath Iron Works led on USS Independence (LCS-2) and USS Coronado (LCS-4). Thirteen ships are under construction, purchased as part of the Navy’s innovative block-buy acquisition strategy.

LCS is a modular, reconfigurable ship, with three types of mission packages including surface warfare, mine countermeasures, and anti-submarine warfare. The Program Executive Office for Littoral Combat Ships (PEO LCS) is responsible for delivering and sustaining littoral mission capabilities to the fleet.

KC-390 prototype

Prototype of the new military transport and multi-mission aircraft KC-390 made by Brazilian company Embraer stopped in the Czech Republic for a few days after being displayed at Farnborough International Airshow. Aero is involved in development and manufacturing of the aircraft and Czech Republic is one of the industrial partners in the KC-390 project.

Aero signed the risk-sharing contract in 2011 during the LAAD Defence & Security exhibition in Rio de Janeiro and it is responsible for design and manufacturing of wing fixed leading edge and for manufacturing of all cabin doors, cargo ramp and rear fuselage of the aircraft. The project of development of KC-390 in Aero is financed by the Czech export bank and insured by EGAP.

The aircraft arrived to the Vodochody Airport at Saturday 16 July at 3 pm. On Monday, it performed two demonstration flights for the representatives of the Czech Republic, including two Deputy Ministers of Defence and Deputy Minister of Foreign Affairs. The KC-390 prototype left Aero on Tuesday 19 July at 10 am.

KC-390 is one of the most important cooperation programs of Aero Vodochody. 150 technicians including engineers and hundreds of workers of Aero are involved in this project and with the dimensions of 6,5 × 4,5 × 3,3 meters – the rear fuselage is the largest aerostructure ever made in the Czech Republic. The aircraft has successfully completed its first flight in February 2015 and it is now in the flight test campaign which should last around two years. Embraer expects to receive the certification of the KC-390 jet by the end of 2017 with first deliveries of the aircraft scheduled for the first half of 2018.

 

KC-390 – about the aircraft

Embraer KC-390 is a tactical transport aircraft designed to set new standards in its category while presenting the lowest life-cycle cost on the market. It can perform a variety of missions such as cargo and troop transport, troop and cargo air delivery, aerial refuelling, search and rescue and forest fire fighting. Equipped with IAE V2500 turbofan engines, the latest avionics, a rear ramp and an advanced cargo handling system, the KC-390 will provide excellent operational productivity and will be capable of transporting a payload of up to 23 tons, including pallets, helicopters, armoured wheeled vehicles, and troops (80 soldiers or 64 paratroopers).

The performance of the KC-390 is benefited by a modern fly-by-wire control system with integrated technology that lowers the workload of the crew and increases the safety of its operation. Furthermore, the KC-390 can refuel other airplanes in flight, with the installation of two removable internal fuel tanks. The aircraft can also be refuelled in flight, thus providing greater flexibility for longer missions. An advanced self-defence system increases the aircraft survival capability in hostile environments.

Surface-launch variant

Lockheed Martin recently conducted a successful controlled flight test of the Long Range Anti-Ship Missile (LRASM) surface-launch variant from the Self Defense Test Ship at Point Mugu Sea Range, California.

Lockheed Martin is the prime contractor for the DARPA/ONR funded Long Range Anti-Ship Missile (LRASM) program that is developing both an air- and surface-launch compatible anti-ship missile that will provide OASuW capabilities

This was the third successful surface-launched LRASM test, proving the missile’s ability to load mission data using the modified Tactical Tomahawk Weapon Control System (TTWCS+), align mission data with the moving ship and launch from the Mk-41 Vertical Launch System (VLS). During the test, LRASM exited the VLS launcher, cleanly separated from its Mk-114 booster and transitioned to the cruise phase. The missile successfully flew a pre-planned low-altitude profile collecting aerodynamics agility data while enroute to its pre-determined endpoint.

«This successful flight test demonstrates Lockheed Martin’s readiness to answer the U.S. Navy’s need for new anti-surface warfare capabilities as part of the ‘distributed lethality’ concept», said Scott Callaway, LRASM Surface-Launch director at Lockheed Martin Missiles and Fire Control. «This LRASM flight test from a U.S. Navy surface ship VLS highlights the successful collaboration between Lockheed Martin and the U.S. Navy».

To support this test, Lockheed Martin invested internal funds to provide an operational LRASM and to refurbish the U.S. Navy’s Self Defense Test Ship Mk-41 VLS. This demonstration from a moving ship in a dynamic at-sea environment was a critical step in proving the maturity of the surface-launch variant. LRASM was also tested successfully from a ground-based Mk-41 VLS «Desert Ship» in 2013 and 2014. Integrating LRASM with the VLS will provide every Aegis destroyer and cruiser with a long-range, survivable anti-surface warfare distributed lethality capability.

The surface-launch LRASM variant was built on the same production line as Joint Air-to-Surface Standoff Missile (JASSM), Joint Air-to-Surface Standoff Missile – Extended Range (JASSM-ER) and LRASM air-launch weapons, and delivers the same long-range, precision capability. With maturity of the Mk-41 VLS integration demonstrated, Lockheed Martin will continue testing on other surface ship applications, including topside, deck-mounted launchers.

LRASM is a precision-guided anti-ship missile that leverages the successful JASSM-ER heritage, and is designed to meet the needs of U.S. Navy and U.S. Air Force warfighters in a robust anti-access/area-denial threat environment. The air-launched variant provides an early operational capability for the U.S. Navy’s offensive anti-surface warfare Increment I requirement to be integrated onboard the U.S. Air Force’s B-1B in 2018 and on the U.S. Navy’s F/A-18E/F Super Hornet in 2019.

Combat vehicle

A live-fire demonstration of weapon systems mounted on a ground mobility vehicle prototype and a light armored vehicle combat reconnaissance vehicle prototype took place on Friday, July 15, at Red Cloud Range on Fort Benning.

The event was sponsored by the Capabilities Development and Integration Directorate Mounted Requirements Division at the Maneuver Center of Excellence, and the General Dynamics Land Systems and General Dynamics Ordnance and Tactical Systems.

«We are in an interwar period here. The interwar period is critical because it is a time when you must leverage an opportunity to get ready for the next conflict», said Major General Eric Wesley, commanding general of the Maneuver Center of Excellence. «If you don’t leverage that opportunity you’re throwing away a resource that has strategic implications».

Wesley explained that cooperation between the U.S. Army and industry is paramount to a successful partnership.

«We need to be cooperating and collaborating with industry and that is what you see here today», said Wesley.

Lieutenant General H. R. McMaster, director of the Army Capabilities Integration Center, spoke about the urgency behind the collaboration with the U.S. Army and industry.

«We are facing threats, enemies and adversaries who have watched us very closely in recent years and have adapted their capabilities and developed new capabilities that have resulted in our forces in the future potentially losing our ability to overmatch the enemy in close combat», said McMaster. «What we are endeavoring to do is to ensure that we stay ahead of these determined and adapted enemies».

McMaster stressed that every combat unit has to have the combination of mobility, protection and lethality in order to overmatch the enemy.

«What we need is a combat vehicle that allows that appropriate combination», said McMaster. «Every time you bump into a U.S. Army formation and you’re the enemy, and you make the unwise choice of taking a shot at us, smoke and boots, that is going to be the result on the other end».

The ground mobility vehicle 1.1 prototype fired an M230-LF 30-mm cannon, while the Light Armored Vehicle (LAV) combat reconnaissance vehicle prototype with a Kongsberg turret fired an integrated MK44 30-mm cannon.

The third and final

In June, the U.S. Navy began conducting Full Ship Shock Trials (FSST) for the Independence variant Littoral Combat Ship (LCS) USS Jackson (LCS-6) off the coast of Florida. The purpose of FSST is to validate the operational survivability of new construction ships after exposure to underwater shock. Three tests were scheduled for the ship and each test was conducted with a 10,000-pound/4,536-kg explosive charge.

On Saturday July 16, USS Jackson (LCS-6) was subjected to the third and final underwater explosion as part of her FSST. There were reports of increased seismic activity around the time of the test. The ship performed exceptionally well, sustaining minimal damage and returned to port under her own power. A large amount of data was collected during FSST on the majority of shipboard systems and the U.S. Navy will compile and analyze the data over the next several months.

Prior to any testing, the U.S. Navy ensures an exclusion zone is established around the test location. A Notice to Mariners (NOTAM) is released before each shot stating that hazardous conditions to surface vessels may be present and for vessels not involved in the test to remain clear. Similarly, the U.S. Navy takes the safety and security of marine mammals seriously, and all testing is executed to avoid the various migration patterns of marine life. Additional lookouts are posted to detect any marine mammal activity and test shots are not conducted if marine mammals are in proximity.

As part of the test program for the Littoral Combat Ship, the U.S. Navy is preparing to conduct FSST on a Freedom variant ship, USS Milwaukee (LCS-5), later this summer off the coast of Florida.

The last FSST was conducted in 2008 for USS Mesa Verde (LPD-19). It was also conducted off the coast of Florida.
