Attacking enemy cruise missiles, fighter jets, helicopters and longer-range high altitude ballistic missiles all present substantial threats to Navy surface ships, especially when multiple attacks arrive simultaneously. By and large, defending against incoming ballistic missiles and air and cruise missiles requires separate defensive systems … until now. A new family of SPY-6 radar systems is being quickly expanded by the U.S. Navy to incorporate a much wider swath of the fleet.

BAGHDAD -- A mock funeral procession marked the anniversary of the assassination of Iran's top general and a senior Iraqi militia leader in a U.S. drone strike that heightened fears of a military escalation in the region. Thousands of mourners joined the march on the highway leading to the Baghdad airport Saturday evening where the strike that killed Gen. Qassem Soleimani and senior Iraqi militia leader Abu Mahdi al-Muhandis took place. Soleimani's killing dramatically ratcheted up tensions in the region and brought the U.S. and Iran to the brink of war.

Center for Security Policy CEO Fred Fleitz provides insight on'America's News HQ.' DUBAI, United Arab Emirates (AP) -- Iran said Saturday it plans to enrich uranium up to 20% at its underground Fordo nuclear facility "as soon as possible," pushing its program a technical step away from weapons-grade levels as it increases pressure on the West over the tattered atomic deal. The move comes amid heightened tensions between Iran and the U.S. in the waning days of the administration of President Donald Trump, who unilaterally withdrew America from Tehran's nuclear deal in 2018. That set in motion an escalating series of incidents capped by a U.S. drone strike that killed a top Iranian general in Baghdad a year ago, an anniversary coming Sunday that has American officials now worried about possible retaliation by Iran. Iran's decision to begin enriching to 20% a decade ago nearly brought an Israeli strike targeting its nuclear facilities, tensions that only abated with the 2015 atomic deal. A resumption of 20% enrichment could see that brinksmanship return.

Alphabet's Wing is less than thrilled with the FAA's new rules for drone'license plates,' and it's pushing for significant changes. Reuters and The Verge report that the drone delivery company has attacked the rules for remote IDs, warning that they might have "unintended consequences" for privacy. Wing argued that the requirement to use locally broadcast remote IDs made it possible to infer "sensitive information" about drone flights and their users, such as where people live or pick up their packages. Internet-based network remote IDs would protect against this kind of privacy intrusion, the company said, claiming that Americans wouldn't accept that potential spying on their "deliveries or taxi trips." The firm also contended that broadcast IDs made it harder to create large-scale drone traffic control systems.

The Pentagon has abruptly sent the aircraft carrier Nimitz home from the Middle East and Africa over the objections of top military advisers, marking a reversal of a weekslong muscle-flexing strategy aimed at deterring Iran from attacking American troops and diplomats in the Persian Gulf. Officials said on Friday that the acting defense secretary, Christopher C. Miller, had ordered the redeployment of the ship in part as a "de-escalatory" signal to Tehran to avoid stumbling into a crisis in President Trump's waning days in office. American intelligence reports indicate that Iran and its proxies may be preparing a strike as early as this weekend to avenge the death of Maj. Senior Pentagon officials said that Mr. Miller assessed that dispatching the Nimitz now, before the first anniversary this Sunday of General Suleimani's death in an American drone strike in Iraq, could remove what Iranian hard-liners see as a provocation that justifies their threats against American military targets. Some analysts said the return of the Nimitz to its home port of Bremerton, Wash., was a welcome reduction in tensions between the two countries.

The president says he will hold Iran responsible if any Americans are killed as the USS Georgia passes through the Strait of Hormuz; Lucas Tomlinson reports. TEHRAN, Iran – The top commander of Iran's paramilitary Revolutionary Guard said Friday that his country was fully prepared to respond to any U.S. military pressure as tensions between Tehran and Washington remain high in the waning days of President Donald Trump's administration. Gen. Hossein Salami spoke at a ceremony at Tehran University commemorating the upcoming one-year anniversary of the U.S. drone strike in Baghdad that killed Revolutionary Guard Gen. Qassem Soleimani, who headed the expeditionary Quds force, on Jan. 3, 2020. At the time, Iran retaliated by launching a ballistic missile strike on a military base in Iraq that caused brain concussion injuries to about 100 U.S. troops. Washington and Tehran came dangerously close to war as the crisis escalated.

John Hopkins, director of Celestial and director of Fare Well, said "For the Hogmanay commission we combined the ancient medium of poetry with our cutting-edge artistry to represent a journey from the past and into a brighter, greener, healthier future."

Two American B-52 bombers flew another show-of-force mission in the Persian Gulf on Wednesday, a week after President Trump warned Iran that he would hold it accountable "if one American is killed" in rocket attacks in Iraq that the administration and military officials blamed on Tehran. The warplanes' 36-hour round-trip mission from Minot Air Force Base in North Dakota was the third time in six weeks that Air Force bombers had conducted long-range flights about 60 miles off the Iranian coast, moves that military officials said were intended to deter Iran from attacking American troops in the region. The United States periodically conducts such quick demonstration missions to the Middle East and Asia to showcase American air power to allies and adversaries. But tensions have been rising in advance of the Jan. 3 anniversary of the American drone strike that killed Maj. Gen. Qassim Suleimani, the commander of Iran's elite Quds Force of the Islamic Revolutionary Guards Corps, and the Iraqi leader of an Iranian-backed militia -- deaths that Iranian leaders repeatedly insist they have not yet avenged.

Recent technological progress in the development of Unmanned Aerial Vehicles (UAVs) together with decreasing acquisition costs make the application of drone fleets attractive for a wide variety of tasks. In agriculture, disaster management, search and rescue operations, commercial and military applications, the advantage of applying a fleet of drones originates from their ability to cooperate autonomously. Multi-Agent Reinforcement Learning approaches that aim to optimize a neural network based control policy, such as the best performing actor-critic policy gradient algorithms, struggle to effectively back-propagate errors of distinct rewards signal sources and tend to favor lucrative signals while neglecting coordination and exploitation of previously learned similarities. We propose a Multi-Critic Policy Optimization architecture with multiple value estimating networks and a novel advantage function that optimizes a stochastic actor policy network to achieve optimal coordination of agents. Consequently, we apply the algorithm to several tasks that require the collaboration of multiple drones in a physics-based reinforcement learning environment. Our approach achieves a stable policy network update and similarity in reward signal development for an increasing number of agents. The resulting policy achieves optimal coordination and compliance with constraints such as collision avoidance.

Autonomous flying'bug drones' that can spy on enemies more than a mile away and operate in strong winds of up to 50mph are being tested by the British Army. Developed by the British defence firms BAE Systems and UAVTEK, 'The Bug' is a fist-sized robot weighing just 6.7 ounces (191g) -- roughly the same as a smart phone. The drone has a 40 minute battery life and a'stealthy low visual profile' that makes it hard for the enemy to spot. The army is said to have taken delivery of 30 units. In the recent Army Warfighting Experiment, the Bug proved to be the only small drone tested that was capable of withstanding difficult weather conditions.
