The F-15E Strike Eagle is a U.S. Air Force two-seat, twin-engine fighter optimized for long-range strike missions. When it comes to costs, public documents typically answer three different questions: (1) a historical per-aircraft unit cost (procurement-era context), (2) a per-flight-hour reimbursable rate (a billing schedule used for reimbursement), and (3) package totals for upgrades or sustainment that bundle hardware, software, spares, training, and support. Those are all “real” numbers, but they are not interchangeable.

TL;DR: Public F-15E numbers range from a historical $31.1 million unit cost anchor to a current per-hour reimbursable rate in the $26,000 range, with multi-billion-dollar support packages sitting above both. That’s roughly $62.1 million in early-2026 dollars (a rough inflation conversion, not a quote for today’s upgrades or lifetime sustainment).

Important numbers

• Historical unit cost anchor of $31.1 million in fiscal year 1998 constant dollars from the Air Force’s published F-15E Strike Eagle fact sheet.
• FY2025 flight-hour rate for an F-15E at $26,480 for FMS users shown in the DoD Comptroller FY2025 fixed-wing reimbursable rates PDF.
• FY2024 flight-hour rate for an F-15E at $28,267 for “all other users” listed in the FY2024 fixed-wing reimbursable rates PDF.
• Upgrade package headline of $6.2 billion in a DSCA notification document for Korea, in the Korea F-15K upgrade notice PDF.
• Sustainment package headline of $3.0 billion in a DSCA notification document for Saudi Arabia, in the Saudi Arabia sustainment notice PDF.

How Much Does an F-15E Strike Eagle Cost?

Start with the unit: the F-15E Strike Eagle.

Per aircraft (historical buy price, translated to today’s dollars): The U.S. Air Force fact sheet pegs the F-15E’s unit cost at $31.1 million in FY1998 constant dollars. If you just want a “today’s money” translation (not a modern replacement price), you can inflate that using CPI-U: the CPI-U annual average for 1998 was 163.0, and the CPI-U index level in January 2026 was 325.252. That’s roughly a 2x move, putting $31.1M at about $62.1 million in early-2026 dollars (a rough inflation conversion, not a quote for today’s upgrades or lifetime sustainment).

Per flight hour (billing proxy, not “what it costs to own the jet”): The DoD reimbursable schedule lists an F-15E “All Other Users” hourly rate of $28,267 in FY2024 reimbursement rates. In FY2025, that same “All Other Users” line is $27,531, which is $736 less per flight hour year over year ($28,267 − $27,531 = $736).

What we verified

• We used the Air Force fact-sheet unit-cost line as the historical per-aircraft anchor (FY1998 constant dollars).
• We used DoD Comptroller reimbursable rate tables for the per-flight-hour anchors (FY2024 and FY2025).
• We used DSCA notification documents to illustrate how upgrade and sustainment package totals bundle hardware, software, spares, training, and support.

Mini real cases

Case 1, per-hour view. The DoD Comptroller publishes reimbursable flight-hour rates used when aircraft are provided on a reimbursable basis. In its FY2025 schedule (effective Oct. 1, 2024), the F-15E row includes multiple user categories, including an FMS-user rate in the mid-$20,000s per hour. These are billing numbers, not a full life-cycle cost, but they are one of the cleanest “per hour” anchors that stays public.

Case 2, package-total view. A DSCA notice for the Republic of Korea lists an estimated total cost of $6.2 billion for an F-15K aircraft upgrade package that includes items like AESA radars and electronic-warfare suites plus software delivery, spares, training, and support. That number is not a “price per jet.” It is a bundled ceiling estimate designed for notification, and these notices commonly state final values can be lower depending on signed agreements and final requirements.

Hidden costs

Public numbers can hide the cost centers that make an operational fleet expensive. One DSCA sustainment notice (Saudi Arabia) illustrates the scope that can sit inside a single headline: spares and repair parts, consumables, repair-and-return support, software support, training, and engineering plus logistics services, all packaged under an estimated $3.0 billion ceiling. These are the quiet drivers that do not show up in a single “unit cost” line.

For broader context, GAO frames the scale of operating and support spending across fleets, noting O&S costs totaled about $54 billion in fiscal year 2020 for the reviewed aircraft in GAO-23-106217. That is not an F-15E invoice, but it explains why a fleet manager can spend more keeping jets ready than buying new airframes.

Worked total example

This example stays inside published fee schedules and uses a short sortie-length profile that appears in another ThePricer cost model. Using the FY2025 reimbursable “all other users” hourly rate of $27,531 and a 2.0-hour profile from a two-hour fighter scramble cost model, one billed F-15E sortie at 2.0 hours would be $55,062 because $27,531 × 2.0 = $55,062.

That figure does not add weapons expenditure, tanker support, or depot impacts, but it shows how a published per-hour rate becomes a cash number once you attach a duration and a billing category.

Modernization line items

Modernization is where “per aircraft” talk gets messy. Electronic warfare, radars, mission computers, and software integration are bought as systems, then installed across a fleet. An Air & Space Forces report ties EPAWSS cost discussions to the older F-15E fleet and cites a program unit acquisition cost of $17.355 million per EPAWSS system in then-year dollars in this Selected Acquisition Report write-up. That is a per-suite number, and it can sit beside separate costs for radar upgrades, wiring work, and test support.

Package totals are the clearest public illustration of “bundled modernization.” The Korea F-15K upgrade notice shows how radar, electronic-warfare suites, mission-computer items, software support, technical documentation, and training can be rolled into a single ceiling estimate for notification.

Sustainment drivers

Sustainment spending is not a single bucket. It shows up as spares pipelines, repair loops, software maintenance, depot throughput, and contractor logistics support, and those lines scale with fleet size and flying hours. GAO’s sustainment overview explains why O&S cost variances can be driven by aircraft type, fleet age, number of aircraft, and flying-hour plans—factors that matter for an aging fleet and for jets cycling in and out of modernization and depot work.

Foreign sustainment notices show how wide the parts-and-support umbrella can be. The Saudi sustainment notice is a clean public example of how a sustainment total can climb without any “new jet” being purchased, because the package is built from spares, repair support, software, training, and service lines.

Who this cost makes sense for

• Makes sense if
  • You need a public per-hour anchor for budgeting discussions and can live with a reimbursable-rate proxy rather than a full O&S model.
  • You are separating modernization from operations, with per-suite items like electronic warfare and radar upgrades treated as distinct line items.
  • You are reading DSCA notices and want to break package totals into hardware, software, training, spares, and support rather than treating the headline as “price per jet.”
  • You are comparing legacy fourth-generation sustainment patterns against newer variants without pretending the reporting units match one-to-one.
• Doesn’t make sense if
  • You want a current “new F-15E” purchase price as if it were an export catalog item.
  • You plan to compare a historical constant-dollar unit cost directly against modern then-year package totals without adjusting for scope and time.
  • You assume a DSCA ceiling estimate is a signed contract value, instead of a notification cap that can come down with final requirements.
  • You need a precise squadron-level sustainment budget without access to contract line items, depot schedules, and flying-hour plans.

Article Highlights

• The Air Force fact sheet lists a historical unit cost of $31.1 million in FY1998 constant dollars, which is context, not a current procurement quote.
• DoD reimbursable rates provide a public per-hour anchor, with FY2025 listing the F-15E in the $26,000 to $27,000 range depending on billing category.
• Package totals can dwarf per-hour and historical unit-cost figures, such as the $6.2 billion Korea F-15K upgrade notice that bundles radars, electronic-warfare suites, software, training, spares, and support.
• Sustainment notices show how spares, repair loops, software support, training, and logistics services can add up even when no new aircraft are bought.
• For comparison shopping across platforms, it helps to see how other military aircraft costs get framed, like Rafale per-jet pricing or B-2 ownership costs.

Answers to Common Questions

Is there a current “new F-15E” price per aircraft?

Not as a public retail number. The Air Force publishes a historical unit-cost statement, but current spending for the Strike Eagle fleet shows up more in upgrades, sustainment, and operating budgets than in new F-15E production pricing.

What does the DoD per-hour rate include?

The reimbursable rates are published for billing when aircraft are provided on a reimbursable basis, and they are presented as hourly charges by user category in the Comptroller rate tables.

Why do DSCA totals look huge compared with per-hour rates?

DSCA notices often bundle equipment, spares, software, training, and engineering plus logistics support into an estimated ceiling value, so the total is a package-scope number rather than a per-jet or per-hour figure.

How does F-15EX reporting relate to Strike Eagle cost talk?

F-15EX unit-cost reporting can be used as a modern Eagle benchmark, but it covers a different variant and includes program assumptions and acquisition reporting that do not map one-to-one to the older F-15E fleet.
