Missing from the left
Only 5 of the 35 outlets with a published leaning rating that ran this story are rated left.
A reader who follows the left would not have seen this. We report the absence rather than explain it: outlets choose what to cover for many reasons, and we have no evidence about which one applies here.
Lockheed Martin unveiled details of its next-generation AIM-260 Joint Advanced Tactical Missile (JATM) on Thursday. The missile is intended to counter long-range air threats from China. The US Defense Department has signed an agreement with Lockheed Martin to increase production of the weapon as part of efforts to rebuild munitions stockpiles. The AIM-260 is designed to be deployed on F-22 Raptor and F-35 fighter jets.
Disagreement on missile's range and effectiveness
The Times of India reported that the AIM-260 offers greater range and effectiveness than existing air-to-air missiles, providing an advantage against Chinese fighter jets like the J-20. None of the other reports mention specific details about the missile's range or effectiveness compared to current weapons.
What the coverage left out
None of the centre or right-rated reports mention the specific details of the agreement between Lockheed Martin and the US Defense Department to boost production, beyond stating that an agreement was signed. The full report from the Times of India mentioned the war in Iran depleted US and allied missile stocks, spurring a push for long-range precision-strike weapons, a detail not present in the other reports.

- USA Today's full report noted Lockheed Martin is investing between $8 billion and $9 billion to increase munitions production. GM CEO Mary Barra stated GM's defense business is a "compelling growth opportunity," with revenue expectations of $700 million by 2026.
- The reports mentioned the Pentagon's initiative to increase weapons production to compensate for depleted stockpiles. None of the left-rated digests mentioned the specific name of the missile, the AIM-260.

Questions about this coverage
- How did the left and right cover Lockheed Martin Unveils AIM-260 Missile for China Threat?
- Of the 35 outlets on this story carrying a published leaning rating, 14% are rated left, 49% are rated centre, 37% are rated right.

- Is Lockheed Martin Unveils AIM-260 Missile for China Threat left or right?
- Neither side dominates it. Of the 35 rated outlets on this story, 14% are rated left, 49% are rated centre, 37% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of Lockheed Martin Unveils AIM-260 Missile for China Threat biased?
- Lockheed Martin Unveils AIM-260 Missile for China Threat is one event reported by 59 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting Lockheed Martin Unveils AIM-260 Missile for China Threat?
