The Independence-class littoral combat ship USS Tulsa has cleared acceptance trials, successfully demonstrating its propulsion plant, handling and auxiliary systems capabilities. Commissioning will come after delivery and post-delivery availabilities, and the ship's home port will be San Diego.
The Navy is planning another ship to be designated the USS Cleveland, says Undersecretary of the Navy Thomas Modly. The littoral combat ship will have an open architecture to accommodate different modular weapons systems.

This is the last call for submissions for the 2018 Combat Systems Symposium. Review the call for papers and submit online by Oct. 15 for consideration.
Hurricane Michael is "very likely" to cause erosion at the bottom of the dune lines of 75% of Florida Panhandle beaches, states a US Geological Survey report that was released Tuesday. "[W]ater levels in some parts of the Northeast Florida coast will still be high enough to overwhelm the dunes, which are relatively low and narrow," says Kara Doran, leader of the USGS Coastal Change Hazards Storm Team in St. Petersburg, Fla.
This month, Los Angeles County Public Works will start the process of restoring Devil's Gate Reservoir in a disputed bid to restore habitat within the Hahamongna Arroyo Seco Watershed, and the removal of 1.7 million cubic yards of sediment is expected to start in April. The project also aims to create "a permanent stormwater maintenance area," as well as replace invasive plant species with healthier species across more than 70 acres of habitat.
Minnesota state agencies are looking into the extent of pollution resulting from sediment discharged from an old gravel mine into the St. Croix River after rain caused the mine to flood. The pollution could be exacerbated by additional rain this week.
Massachusetts' coastal areas have been taking big hits from major storms and rising seas, leading many people along the coast to advocate for greater legal leeway to erect protective seawalls. But while seawalls may shield homes, environmentalists contend that restrictions are necessary, as the structures can accelerate erosion and reduce the integrity of beaches.
The $300,000 Sherman Green flood mitigation project in Fairfield, Conn., was itself flooded by heavy rains last week. "[The project] will definitely help matters, but it won't totally fix the problem, as there is just too much water for the system to handle during these intense rainfall events," said Community and Economic Development Director Mark Barnhart.
Saving the Everglades is a practical matter for South Floridians, as the natural habitat is also a hurricane buffer and a source of drinking water, writes the Sun Sentinel Editorial Board. The best method to address rising sea water encroaching from the south is to restore fresh water flow into the area, the board writes.
