The United States Marine Corps has accepted delivery of six F-35B fighter jets without their primary radar systems installed, confirming that the military is now taking new aircraft from the production line missing one of its most critical combat components.

The aircraft lack the AN/APG-85 radar, a next-generation system developed by Northrop Grumman that is central to the F-35's Block 4 modernization program. Instead of the radar, the nose of each aircraft carries ballast, meaning heavy material used to maintain proper weight and balance. The first production lot of the AN/APG-85 is scheduled for delivery in April 2028, representing a nine-month improvement from earlier timelines but still years behind the original plan.

The decision affects jets built under Lot 17 production, which include a redesigned nose bulkhead specifically intended to accommodate the new radar. Because the mounting hardware for the APG-85 does not match the mounting points of the older AN/APG-81 radar, switching to the new system has proven more complicated than expected. The radars are purchased separately by the government directly from Northrop Grumman rather than through Lockheed Martin, the prime contractor for the F-35 aircraft itself.

The Marine Corps and the F-35 Joint Program Office, led by Marine Corps Lt. Gen. Gregory Masiello, defended the decision as a deliberate choice. They said it was better to keep building new jets that can later receive the new radar than to keep building older Block 3 aircraft that would require extensive retrofitting later. The program office stated the decision was made with full understanding of the risk of having production aircraft ready ahead of new capabilities. However, Lt. Gen. Masiello acknowledged during a Senate Armed Services Committee hearing that jets without radars cannot be considered fully mission capable.

Aircraft without functioning radars can still be used for basic flight training but cannot participate in combat training or operational missions. No Air Force or Navy F-35s have been delivered without radars at this point, but both services are expected to receive such aircraft before the end of the year. The Air Force is exploring a solution that would allow both radar types to fit in the same aircraft nose, though that fix could take two years. In the meantime, the Air Force has set aside $133 million in 2031 to upgrade 14 of its F-35A jets with the new radar at approximately $9.5 million per jet, with plans to spend roughly $1.6 billion more to upgrade another 167 aircraft.

The disclosure came during a Senate Armed Services Committee hearing where Senator Mark Kelly of Arizona, a retired naval aviator, pressed Lt. Gen. Masiello on the program's declining readiness rates. A Government Accountability Office report released in June found that the average full mission capable rate across all F-35 variants dropped from 38 percent to 25 percent between Fiscal Years 2020 and 2025. The share of aircraft able to perform at least some missions was 44.1 percent, down from 67 percent in 2021. The Joint Program Office's own calculation puts the mission capable rate at 56 percent, citing different counting methods, but Lt. Gen. Masiello did not dispute the GAO numbers directly. He stated that reaching an 80 percent mission capable rate by 2030 remains the stated goal, a target originally directed by then-Secretary of Defense Jim Mattis in October 2018.

The radar delay comes at a time when the F-35 program faces broader readiness and sustainment challenges. The support system that keeps the jets flying was originally designed for a fleet of 700 to 800 aircraft, but the total number of F-35s delivered worldwide has now surpassed 1,300. Across all branches, the Air Force, Navy, and Marine Corps operate 832 F-35 jets from 42 bases and 13 ships. Lt. Gen. Masiello blamed years of not buying enough spare parts as the fleet grew, describing the issue as a matter of stocking rather than a systemic inability. The program has launched a $13.7 billion effort through 2031 to address spare parts, repair depots, and maintenance plans.

Power and cooling constraints are also slowing modernization. The current F-35 cooling system provides about 32 kilowatts, while future systems will eventually need cooling for equipment drawing between 62 and 80 kilowatts. Lt. Gen. Masiello described the current plan as offering no margin and said using all available power without margin is not a smart approach. An upgrade to the Power and Thermal Management System is anticipated in 2031, tied to Pratt and Whitney's upgraded engine core design, with further upgrades expected several years after that. A next-generation engine that could have provided more cooling was explored but deemed too expensive and was not funded.

The Block 4 modernization program, intended to improve the fighter's sensors, computing power, electronic warfare, and weapons systems, has been plagued by cost growth and schedule delays. Of 55 planned Block 4 features, 22 have been fielded, with six more expected this year. The full suite is now years past its original 2026 target. The program also plans to change contracts to add stronger rewards and penalties after criticism that contractors were paid millions even as readiness declined.

The government has made 46 recommendations since 2014 to improve support and readiness, but only 14 had been carried out by March. The program chief declined to give a specific number for how many have been closed, saying all are likely in progress. The total projected lifecycle cost of the F-35 program from the 1990s through the end of its expected life in the 2070s is $2.1 trillion, with inflation expected to account for roughly half of that figure. The Pentagon's long-term budget plan includes more than $13 billion for the broader sustainment effort.

Further details about the specific capabilities of the APG-85 radar and its cooling requirements were addressed in a classified portion of the Senate Armed Services Committee hearing.

This article provides no actionable information for a normal person. It reports on military procurement problems and congressional hearings, but it offers no steps, choices, instructions, or tools a reader can use. There are no resources mentioned that an individual can access or act upon. A person reading this cannot influence the F-35 program, verify the readiness figures, or apply any of the information to daily life. The article gives the reader nothing to do.

The educational depth is limited. The article mentions that fighter jets were delivered without radars, that readiness rates dropped from 38 percent to 25 percent, and that the total lifecycle cost is estimated at $2.1 trillion. However, it does not explain how military procurement actually works, why radars are delayed, what factors determine whether a jet is mission capable, or how the GAO calculates readiness rates. The numbers appear without context about what counts as good or bad performance, how these figures compare to other aircraft programs, or what causes cost growth in defense projects. The information stays at the surface level of reporting claims without teaching the reader how to understand these systems.

Personal relevance is small for most readers. The article might matter directly to people who work in defense procurement, military aviation, or government oversight. For an ordinary person elsewhere who has no direct connection to these programs, the information does not change how they should manage their safety, money, health, or daily responsibilities.

The public service function is weak. The article does not warn any specific population about an imminent danger in a way that helps them act. It notes declining readiness rates and rising costs but provides no guidance on how taxpayers can evaluate defense spending, how citizens can hold programs accountable, or how to assess whether military procurement represents good value. It exists mainly as a summary of a congressional hearing rather than as a service to help people act responsibly.

There is no practical advice in this article for an ordinary reader to follow.

The long term impact of reading this is minimal for personal action. It may slightly increase awareness that military programs face delays and cost overruns. It does not give the reader tools to evaluate similar claims critically in future news cycles or to apply lasting principles when judging government spending or procurement stories.

The emotional impact leans toward mild concern without offering any constructive response. The article describes problems with expensive military equipment but does not balance this with practical guidance about how citizens can engage with these issues, how to evaluate whether spending is justified, or how to make informed decisions about defense policy. The reader is left aware of a problem without gaining tools to respond to it.

The language is measured and not overtly clickbait. Phrases like "significant development" and "troubled history" add some weight but do not sensationalize. The article does not use exaggerated numbers or false claims. It presents facts from a congressional hearing without obvious distortion.

The article misses several chances to teach broader lessons. It could explain how citizens can evaluate whether government programs are well managed, what questions to ask when hearing about cost overruns, how to compare performance metrics across programs, or what general principles apply to any large project that spends public money. It could also explain how procurement delays affect readiness and what tradeoffs exist between accepting incomplete equipment and waiting for finished products.

A person who wants to keep learning can use basic reasoning methods without relying on external data sources. Compare claims by checking whether multiple independent oversight bodies report similar problems with the same program. Examine patterns by watching whether cost overruns and delays continue over several years or improve after leadership changes. Consider general principles. When a program says accepting incomplete equipment is a deliberate strategy, ask whether the explanation makes sense or simply reframes a failure as a plan. These questions require only common sense.

Here is concrete guidance based on universal principles that readers can apply regardless of location. When you hear about a government program with rising costs and delays, ask what specific oversight exists and whether independent auditors can verify the claims. When someone tells you that accepting a flawed product is part of a strategy, consider whether the same explanation could be used to justify any failure. When you encounter large numbers like trillion dollar estimates, ask what that money could otherwise fund and whether the benefits justify the cost. When you read about declining performance metrics, ask what counts as acceptable performance and who sets that standard. When you want to influence how public money is spent, learn which elected representatives oversee the relevant programs and what questions they ask in public hearings. Clear, documented, supported efforts to understand how your money is spent are more effective than relying on a program's assurances alone.

The text uses the soft phrase "significant development" to describe accepting fighter jets without radars. This word trick hides how bad the problem is by making it sound like normal progress instead of a serious failure. The bias helps the Marine Corps and the F-35 Joint Program Office look better by downplaying the fact that they took broken jets. A clearer phrase would say they accepted broken planes that cannot do their main job.

The text says the radar is "not expected to be delivered until 2028 due to ongoing development challenges." This soft language hides who is really at fault for the delay. The passive voice removes responsibility from Northrop Grumman and the program office by making the delay sound like a natural event rather than a failure they caused. The words help the defense contractor and the military avoid blame for not delivering on time.

The text calls the Block 4 program "plagued by cost growth and schedule delays." This strong negative language makes the program sound like it has serious problems. But then the text says accepting radarless jets was "part of a deliberate strategy" to avoid building older jets. This word trick tries to make a bad situation sound like a smart plan. The bias helps the program office by turning a failure into a clever choice.

The text says the jets "cannot be considered fully mission capable without their radar systems." This is a soft way to say the jets are broken and useless for fighting. The phrase hides the real meaning by using technical words instead of saying the planes cannot do their job. The bias helps the military by making broken jets sound like they just need one small fix.

The text mentions "a nine-month improvement from previous timelines but still years behind original plans." This word trick tries to make the program look better by focusing on a small improvement. The bias helps the F-35 program by hiding how far behind schedule they really are. The words push readers to feel good about a small change instead of angry about years of delays.

The text says the total lifecycle cost is "estimated at $2.1 trillion through the 2070s." This huge number is placed at the very end with no explanation of what it means for taxpayers. The bias helps the program by burying the shocking cost where readers might miss it or feel too tired to care. The order of words hides how much money is being spent on broken jets.

The text uses the phrase "troubled history of the Joint Strike Fighter program" in the first sentence. This strong negative setup makes the whole program sound bad from the start. But then the text gives excuses for why broken jets were accepted. The bias helps critics of the program by starting with a harsh tone, but then helps the program by explaining away the problems. The mixed message confuses readers about who is really at fault.

The text says Senator Mark Kelly "pressed the general on the program's declining readiness rates." This word trick makes the senator sound aggressive and the general sounds like a victim. The bias helps the military by making the person asking hard questions seem pushy. The words hide that the senator was just doing his job to check on problems.

The text mentions "thermal management issues that will require significant power and cooling upgrades." This technical language hides a serious problem with plain words about heat and power. The bias helps the program by making a big flaw sound like a normal engineering challenge. The soft words hide that the jets might not work right without major fixes.

The text says the GAO report showed readiness rates "dropped from 38 percent to 25 percent." This fact is stated with no strong words to show how bad it is. The bias helps the program by making a huge drop in working jets sound like just a number. The plain words hide that most jets cannot do their job most of the time.

The text uses the phrase "keep the F-35 competitive against future threats" to explain why the radar matters. This word trick makes the program sound important for national security. The bias helps the military and contractors by making readers feel scared about threats. The words push support for spending more money by making the jets seem needed for safety.

The text says the Marine Corps and program office "defended the decision" to accept radarless jets. This word trick makes their choice sound reasonable and worth defending. The bias helps them by making a bad decision look like a smart plan. The words hide that they had no good choice because the radars were not ready.

The text mentions "spare parts shortages and rising operational costs" as part of broader challenges. This soft language hides how badly the program is run. The bias helps the military by making big problems sound like normal issues every program has. The words hide that this program costs way more than planned and still cannot keep jets working.

The text conveys a sense of frustration that runs throughout the discussion of the F-35 program's ongoing problems. This frustration appears in the description of the program as having a "troubled history" and in the mention of readiness rates that "dropped from 38 percent to 25 percent." The word "troubled" carries emotional weight because it suggests repeated failures and persistent difficulties rather than a single isolated problem. The frustration is moderate in strength and serves to make the reader feel that something has gone seriously wrong with a program that should be working better. It guides the reader toward questioning whether the program is being managed well and whether the money being spent is producing good results.

A second emotion is concern, which appears in the description of the jets being delivered without radars. The text states that the jets "cannot be considered fully mission capable without their radar systems," which creates worry about whether these expensive aircraft can actually do their job. The concern is moderate to high in strength because it touches on national security and the safety of military personnel who depend on working equipment. This emotion serves to make the reader feel uneasy about the gap between what was promised and what was delivered. It guides the reader to see the situation as a serious problem rather than a minor technical detail.

A third emotion is defensiveness, which comes through in the way the Marine Corps and the F-35 Joint Program Office "defended the decision" to accept radarless jets. The word "defended" suggests that they felt under attack and needed to justify their actions. This defensiveness is mild to moderate in strength and serves to show that the program officials know their decision looks bad and need to explain it away. It guides the reader to see the officials as being on the back foot, trying to put a positive spin on a situation that is hard to defend. The phrase "deliberate strategy" reinforces this defensiveness by attempting to reframe a failure as a smart plan.

A fourth emotion is disappointment, which appears in the discussion of the radar delays. The text notes that the radar delivery date represents "a nine-month improvement from previous timelines but still years behind original plans." The word "but" carries emotional weight because it shifts from a small positive to a much larger negative. The disappointment is moderate in strength and serves to make the reader feel that even the good news is actually bad news when seen in context. It guides the reader to see the program as falling short of expectations despite claims of progress.

A fifth emotion is alarm, which appears in the mention of the "total projected lifecycle cost estimated at $2.1 trillion through the 2070s." This enormous number creates a sense of shock and worry about how much money is being spent. The alarm is moderate in strength and serves to make the reader feel that the cost is out of control. It guides the reader to question whether this spending is justified and whether taxpayers are getting good value for their money.

These emotions work together to guide the reader toward feeling skeptical about the program and concerned about its direction. The frustration and disappointment draw attention to repeated failures, while the concern and alarm highlight the seriousness of the problems. The defensiveness adds a layer of tension by showing that program officials know they have explaining to do. The overall effect is to make the reader view the program as troubled and worthy of scrutiny rather than as a success story.

The writer uses several tools to increase emotional impact. One tool is the use of strong descriptive words like "troubled," "plagued," and "declining," which make the problems sound worse than neutral language would. Another tool is the contrast between small improvements and large failures, such as noting a nine-month improvement while emphasizing that the program is still years behind schedule. This contrast makes the good news feel hollow and reinforces disappointment. The writer also uses specific numbers, like the readiness rate drop and the trillion-dollar cost, to make the problems feel concrete and real rather than abstract. The placement of the cost figure at the end of the text creates a lasting impression that leaves the reader with a sense of alarm. The writer also uses the hearing setting to create tension, showing a senator pressing a general on problems, which adds a sense of accountability and conflict. These tools work together to steer the reader toward viewing the program critically and feeling that serious problems need to be addressed.
