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.

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. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 59. The sections above set out what each side emphasised, in its own terms.
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?
When we first saw this story, outlets rated left had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
Which outlets covered Lockheed Martin Unveils AIM-260 Missile for China Threat?
59 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.

The AIM-260 Joint Advanced Tactical Missile, or JATM, is a next-generation air-to-air missile developed by Lockheed Martin. It is designed to counter long-range air threats, particularly from China, and will be deployed on F-22 Raptor and F-35 fighter jets.
Why is the US boosting production of this missile?
The US Defense Department has signed an agreement with Lockheed Martin to boost production of the AIM-260 as part of efforts to rebuild munitions stockpiles. Reports suggest this is a response to depleted missile stocks following conflicts.
Which countries are purchasing the AIM-260 missile?
The United States is increasing production of the AIM-260 missile. Australia has also announced it will purchase approximately $521 million worth of JATM missiles, though the quantity and unit price were not disclosed.
