SpaceX, Northrop Grumman Complete First Tests for Golden Dome Missile Shield

SpaceX and Northrop Grumman, among the firms building space-based interceptors for the $185 billion Golden Dome missile defense program, completed initial key tests. The Pentagon is incorporating new AI-driven tracking technologies ahead of planned 2027 flight demonstrations.

Space-based interceptors clearing early tests is a long way from a working shield; whether the AI tracking layer performs matters far more than today's milestone.

OpenAI Expands Daybreak, Launches GPT-5.6-Cyber

OpenAI expanded its Daybreak cyber-defense program with two tiers, Blue and Red, and released GPT-5.6-Cyber, a model purpose-trained for authorized vulnerability research and exploit validation. OpenAI says the model completed 95 percent of advanced cybersecurity tasks in testing, compared with 1.5 percent for the base model.

A jump from 1.5 percent to 95 percent on OpenAI's own benchmark is the kind of number that demands independent replication before anyone treats it as ground truth.

SpaceXAI (xAI) Launches Grok Bot Public Beta

xAI, rebranded SpaceXAI, launched a public beta of Grok Bot, an agentic tool that can sign into apps and websites and share context across tasks like a team of AI agents. Musk signaled a wider rollout tied to Grok 4.6 later in the week.

Letting an agent sign into your own accounts is a much bigger trust ask than a chatbot, and credential handling is what will make or break adoption of this class of tool.

Will money run out for Golden Dome?

A recap from the first day of the 2026 Space and Missile Defense Symposium covered leading news, including questions about whether funding will hold up for the Golden Dome missile defense program.

Funding doubts surfacing on day one of the industry's own missile-defense symposium is not a great sign, though this recap doesn't say how large the shortfall talk is.

Island surge: The Army’s Next Generation Command and Control in action

This sponsored piece describes Lightning Surge exercises turning soldier feedback on the Army's Next Generation Command and Control system into operational software changes within days.

Sponsored content aside, fast field-to-software iteration on battlefield C2 solves the usual bottleneck in military software, if it's real.

Joby to buy Resonant Sciences, establish defense business in $500 million deal

Joby is acquiring Resonant Sciences to establish a defense business, in a $500 million deal funded by roughly $450 million in cash and $50 million in Joby common stock. The deal is expected to close in the first half of 2027.

Joby buying its way into defense revenue underscores how hard it still is to win Pentagon business on commercial drone merits alone.

More reach, more to carry, more to learn: How soldiers wrestled with drones in the Mojave Desert

Project Convergence Capstone 6 in the Mojave Desert produced lessons for soldiers using drones, measured in capability, reliability, weight, and the harsh desert conditions they operated under.

Weight and reliability complaints from soldiers in the field are the unglamorous data that actually shapes procurement, more than any demo video.

Stealing Reasoning Traces from Proprietary LLM APIs

A new paper shows that encrypted chain-of-thought blocks returned by Anthropic, OpenAI, and Google APIs can be replayed across sessions, users, and models. Researchers took a trace from a frontier model, replayed it into a weaker sibling model, jailbroke that weaker model, and recovered the stronger model's hidden reasoning in plaintext.

That encryption blocks casual inspection. It does not stop a determined attacker who actually wants the reasoning inside, so do not build anything that assumes those traces stay hidden.
