哥偶然在Aviation Week 找到這篇文章文章中說:
Lockheed Martin has delivered six F-35Bs to the U.S. Marine Corps without radars due to ongoing delays with a powerful new upgrade, the head of the F-35 Joint Program Office (JPO) told lawmakers on June 23.
洛克希德•馬丁公司已向美國海軍陸戰隊交付了六架F-35B，但這些飛機未安裝雷達，原因是某項強大的新升級項目持續延誤，F-35聯合計畫辦公室（JPO）負責人於6月23日向國會議員如此表示。
The Marine Corps chose to wait for the arrival of the Northrop Grumman APG-85 active electronically scanned array (AESA) radar rather than accept F-35Bs equipped with the existing radar, Lt. Gen. Gregory Masiello said during a Senate Armed Services Committee hearing.
海軍陸戰隊選擇等待諾斯洛普•格魯曼公司APG-85主動電子掃描陣列（AESA）雷達的到來，而不願接收配備現有雷達的F-35B，葛列格里•馬謝洛中將在參議院軍事委員會聽證會上如此表示。
The APG-85 reportedly requires modifications to the internal bulkhead and structure in the nose of the F-35 compared to the baseline version with the Northrop APG-81. Most details about the APG-85 radar performance within the U.S.-only portion of the Block 4 upgrade program remain classified.
據報導，與配備諾斯洛普APG-81的基本型相比，APG-85需要對F-35機頭內部的隔框和結構進行修改。關於
APG-85雷達性能的大部分細節，屬於Block 4升級計畫中僅限美國的部分，仍屬機密。
Sen. Mark Kelly, a former Navy fighter pilot, also linked the future performance of the radar to a power and thermal management system (PTMS) upgrade now underway for the F-35’s Pratt & Whitney F135 engine.
前海軍戰鬥機飛行員、參議員馬克•凱利還將該雷達的未來性能，與目前正在為F-35的普惠F135引擎進行的電力與熱管理系統（PTMS）升級聯繫起來。
“Right now you’re cooling [system supports] about 30 kW [of waste heat],” Kelly said. “Block 4 requires 32 [kW] is what I have here. But to get to the cooling needed for the full capability of the APG-85, it needs to be somewhat higher. It seems like 62 kW of cooling?”
「目前你們的冷卻（系統支援）約30千瓦（的廢熱），」凱利說。「Block 4需要32千瓦，這是我這邊的數據。但要達到APG-85完全能力所需的冷卻，還需要更高一些。看起來是需要62千瓦的冷卻？」
Masiello sidestepped directly answering the question about the power needs of the APG-85, but said the overall power and thermal management system program is aiming to produce 62-80 kW.
馬謝洛迴避了直接回答關於APG-85電力需求的問題，但他表示，整體電力與熱管理系統計畫的目標是達到62至80千瓦。
But Masiello said that the PTMS upgrade will not be required or available at the time that the APG-85 is ready to be installed on the six F-35Bs that the Marine Corps has received so far without radars. An initial version of the PTMS with incremental improvement will arrive by fiscal 2031, Masiello said, with the full capability arriving a few years later. But the APG-85 will be ready before fiscal 2031.
但馬謝洛表示，當APG-85準備好安裝在這六架海軍陸戰隊已接收但未配備雷達的F-35B上時，PTMS升級既非必要也尚不可用。馬謝洛說，具備漸進式改良的PTMS初始版本將在2031財年之前到位，而完整能力則會在幾年後才出現。但APG-85會在2031財年之前就準備就緒。
Masiello also agreed to discuss any performance shortfalls with the APG-85 radar before the cooling system upgrades arrive with Kelly in a classified follow-on hearing.
馬謝洛也同意，在冷卻系統升級到來之前，與凱利在後續的機密聽證會中討論APG-85雷達的任何性能不足之處。

哥真沒想到美國的航空工業已經拉胯到這種地步 , F-35問題重重 難怪美軍在2021年就承認
F-35專案失敗
