Navy awards $6-million contract for cleanup of World War II hangar in Tustin that burned

Navy officials announced this week that a $6-million contract has been awarded to an environmental cleanup firm to remove the debris that were released when an historic 17-story hangar in the city of Tustin caught fire.

There is no start date yet for the work awarded to ECC Environmental LCC.

The fire at one of two blimp hangars built in 1942 started Nov. 7 and burned for 24 days. The south hangar was not damaged. The two structures were part of a Marine Corps. air station that closed in 1997. The cause of the fire remains under investigation, according to city officals.

The Navy has agreed to pay Tustin $11 million toward the cleaning and repairs from the damage caused when fumes and debris from the fire drifted through the city. Tustin officials reported that the cost associated with the recovery may exceed $100 million. As the fire burned, residents feared that ash and debris from the World War II-era hangar contained asbestos.

DoD outlines four-phase approach to implement CMMC in proposed rule

The Defense Department’s long-awaited proposed rule for the Cybersecurity Maturity Model Certification program lays out DoD’s plan to introduce the CMMC requirements over the next three years.

The proposed rule, released today and scheduled to be published in the Federal Register on Dec. 26, would establish requirements “for a comprehensive and scalable assessment mechanism” to ensure defense contractors are implementing required security protections.

DoD already has a provision in its contracts requiring companies that handle controlled unclassified information to protect it in accordance with controls set by the National Institute of Standards and Technology.

But DoD has not typically checked whether contractors actually follow those requirements. And with persistent and mounting concerns about foreign adversaries stealing sensitive data from the networks of defense contractors, the CMMC program is intended to check whether companies meet the standards before contract award.

Rotating Detonation Sparks GE Path To Hypersonic Future

Steve Trimble December 19, 2023

A state-of-the-art ramjet struggles to accelerate when activated below approximately Mach 3.5. The insides of a supersonic turbofan start melting at speeds above Mach 2.5. To invent a reusable, air-breathing propulsion system for a hypersonic vehicle, technologists must find a solution to the yawning gap between the top speed of a turbofan and the minimum speed of a ramjet.

As both a latecomer to the current hypersonic propulsion race and a decades-old veteran of high-Mach research, General Electric thinks it has discovered the missing piece: a rotating detonation combustor.

By harnessing the powerful energy release that comes from fuel detonation, the company that built the Mach 3 engines to power the North American XB-70 Valkyrie bomber and the canceled Boeing 2707 airliner half a century ago thinks it can lower the Mach number for the cutover speed between a turbofan and a ramjet low enough to make a full-scale, turbine-based combined-cycle (TBCC) propulsion system feasible at speeds faster than Mach 6.

you weren't suppose to pick one adventure and put it down when you were done .

You had to explore all routs of possibility.

If you did the math you were able to calculate choices, there were a lot of stories how that played out in one book.

The word of God is the most fascinating, when choosing your own adventure.
