In December 2020, new US sanctions came into force. The United States has tightened export controls. The sanctions list includes 45 Russian companies. Among them was the manufacturer of titanium and JSC VSMPO-AVISMA.

A team of scientists from the Massachusetts Institute of Technology has developed a new type of Kevlar-based molecules that can self-assemble into long strands. Their thickness is only one nanometer, while the length and area can vary depending on the tasks set. The first experiments showed that these thinnest threads are incredibly strong, and therefore have a wide range of potential applications.

For the PD-35 high-power engine, the United Engine Corporation manufactures wide-chord fan blades from polymer composite materials using prepregs and 3D-weaving technology.

The US Navy stops the supply of Freedom-class coastal ships

The US Navy has suspended deliveries of the Lockheed Martin Corporation's Freedom-class coastal zone ship. The reason for the rejection of the vessel was a structural defect in the power transmission. This is not the first problem faced by American shipbuilders in recent years, which causes wariness in the expert community.

The British company Supacat has completed the development of a set of conversion of Jackal 1 diesel armored vehicles into hybrid ones without loss of driving characteristics. According to Jane's, the company also prepared the first such armored vehicle for the installation of the kit and testing. All work was completed in mid-December last year, but the company announced this only now.
