China’s DF-27 Missile: Threatening Pacific Ships and the U.S. Homeland
Maritime Executive – Among the 2025 Pentagon report’s greatest revelations, the People’s Republic of China (PRC) has fielded a conventional intercontinental ballistic missile (ICBM) able to range parts of America’s homeland. This makes China the first nation publicly assessed to have fielded an operational, conventionally-armed ICBM—the DF-27—albeit at the low end of the ICBM range band and with variant-dependent roles. America’s homeland is not a sanctuary from either PRC nuclear or conventional missiles.

Navy’s New Frigate Will Not Have A Vertical Launch System For Missiles
The War Zone – The U.S. Navy has confirmed that the armament package for its first “flight” of its new FF(X) frigates will not include a built-in Vertical Launch System (VLS). A lack of any type of VLS on the FF(X) design is a glaring omission that can only raise questions about the operational utility and flexibility of the ships. At the same time, the new frigates will be able to carry modular payloads, including containerized missile launchers, on their sterns.
Pax Americana to Pax Sinica
Australian Naval Institute – Guided by Geoffrey Till’s emphasis on naval balance and freedom of navigation[i], this essay argues that China’s expanding naval posture near Australia signals a contested transition from Pax Americana to a prospective Pax Sinica.

CMSI Translations #25: A New Pillar for Distant Oceans: Concepts for the Chinese Navy’s New Generation of General-Purpose Destroyers
China Maritime Studies Institute – A recent unconfirmed rumor about the Chinese Navy developing a new general-purpose guidedmissile destroyer has stirred debate online. Many commenters argue that the Type 055 already offers exceptional capability across air defense, missile defense, anti-ship, anti-submarine, and general warfare roles, and is more than capable of meeting current mission needs. But because it’s expensive to build, it is not practical to produce in large numbers or to use for routine tasks, so it will likely remain a smaller part of the fleet. In contrast, the more affordable Type 052D class is limited by its size and displacement, which restricts how much it can be upgraded. As a result, it still cannot match the endurance or sustained firepower of the U.S. Navy’s Arleigh Burke-class destroyers.
