The short version

• The cross waiver is the defining feature of a launch services agreement. Everyone bears their own losses regardless of fault, and the waiver flows down the entire contract chain.
• US law requires it. 51 U.S.C. 50914 and 14 CFR 440.17 make reciprocal waivers a condition of a licence.
• Above the waiver sit three tiers: mandatory insurance sized to maximum probable loss, government indemnification up to $1.5 billion indexed from 1989, and then the operator again, uncapped.
• The indemnification tier has never been triggered and Congress has never appropriated against it. Its current expiry is 30 September 2028.

A launch failure is the rare commercial event that can generate claims in every direction at once. The launch provider’s vehicle destroyed the customer’s satellite. The satellite’s failure damaged the pad. A component supplier three tiers down may have caused all of it. Government range equipment was involved. Several insurers are subrogated to several of those claims.

Litigated conventionally, one failure produces a decade of circular claims in which every participant sues every other participant and most of the money goes to lawyers.

The industry solved this in the 1980s and has not changed the solution since.

What a cross waiver does

A cross waiver is a reciprocal, no-fault waiver of claims. Each participant in a launch agrees to bear its own property damage and its own employees’ injuries, and waives claims against every other participant, regardless of fault.

The participants are drawn widely: the launch provider, the customer, their contractors and subcontractors at every tier, crew and spaceflight participants, and the US government. Each party must flow the waiver down its own contract chain, so a fourth tier supplier is inside the ring even though it has no contract with the launch provider.

The effect is to convert an interlocking commercial and governmental supply chain into a set of self-insured silos. Each party insures its own property, prices that into its contract, and stops worrying about who was at fault.

Two standard exceptions survive. Wilful misconduct, and claims exceeding the required insurance amounts.

The cross waiver does not touch third party claims by uninvolved people on the ground. Those are handled by the insurance and indemnification tiers below.

Where the requirement comes from

This is not purely a matter of negotiation. US law mandates it.

51 U.S.C. 50914(b) requires a launch or reentry licence to contain reciprocal waivers among the licensee, its contractors, subcontractors, customers and spaceflight participants, each assuming responsibility for its own employees’ injuries and property losses. It also requires the Secretary of Transportation to negotiate reciprocal waivers protecting the government, its agencies and its contractors, except for claims exceeding the required insurance.

14 CFR 440.17 supplies the detail. Waivers are required between the licensee and its contractors and subcontractors and the first tier customer and its contractors and subcontractors, with spaceflight participants, and with crew.

An operator that wanted to negotiate this away could not. It is a licence condition.

The three tiers above the waiver

Third parties, meaning people who are not participants in the launch, are not covered by the cross waiver. For them there is a structure.

Tier one: mandatory insurance sized to maximum probable loss

Under 51 U.S.C. 50914(a) a licensee must obtain liability insurance or demonstrate financial responsibility to cover maximum probable loss from third party claims and from claims for damage to US government property.

MPL is defined at 14 CFR 440.7 as the greatest dollar amount of loss for bodily injury or property damage reasonably expected from the licensed activity. The FAA issues a determination within 90 days of a complete request.

The probability thresholds are the technical heart of the regime. One in ten million for third parties. One in one hundred thousand for government personnel and property. Losses less probable than those thresholds are excluded from the calculation.

Statutory caps sit above the calculation: $500 million for third party liability insurance and $100 million for government property, or the maximum available on the world market at reasonable cost if that is lower.

Duration matters too. Launch cover runs until 30 days after payload separation, and reentry cover for 30 days from initiation of reentry. Certificates of insurance are due at least 30 days before activities begin.

Tier two: government indemnification

Under 51 U.S.C. 50915 the government may pay successful third party claims above the required insurance, up to $1.5 billion plus amounts reflecting inflation after 1 January 1989.

The qualifier is decisive. Payment is available only to the extent provided in advance in an appropriation law or to the extent additional legislative authority is enacted. Congress has never appropriated against it and it has never been triggered.

Tier two is therefore a promise to consider paying, not a guarantee of payment. Anyone modelling it as a hard backstop is modelling something that does not exist.

Tier three: the operator, uncapped

Claims above the indemnification ceiling fall back on the licensee, with no cap. In practice a loss of that size would be an insolvency event.

The expiry date to diarise

Under 51 U.S.C. 50915(f), the indemnification regime applies to a licence issued or transferred for which the Secretary receives a complete and valid application not later than 30 September 2028. That date was set by Pub. L. 118-159 on 23 December 2024, extending it from 30 September 2025.

Note the trigger precisely, because secondary commentary garbles it regularly. It is the date the FAA receives a complete and valid application, not the date of the launch. A licence applied for before the deadline carries the regime with it.

Given the history of short serial extensions, plan on it being extended again and do not build a business case on the assumption.

Drafting points that matter

Flow down is the weak link

The cross waiver only works if every participant is inside it. The commonest failure is a subcontract deep in the chain that omits the flow down, usually because it was papered on a supplier’s standard terms for a component that nobody thought of as launch related. Audit the chain, do not assume it.

Define the participants by reference, not by list

Personnel and suppliers change between signature and launch. A defined class that captures contractors and subcontractors at every tier is more robust than a schedule of named entities.

Wilful misconduct is narrower than it sounds

The exception is not gross negligence and it is not recklessness in the loose sense. Parties who assume it gives them a route back into the ring after a failure are usually disappointed.

Insurance and the waiver must line up

If the cross waiver allocates a loss to a party whose policy does not cover that loss, the waiver has created an uninsured exposure. This is a coordination problem between the contract team and the insurance broker and it is where most real risk sits. We look at the market side in our piece on space insurance.

Non-US launches follow a similar shape

European launch contracts through Arianespace, and licences under the UK Space Industry Act 2018 or India’s IN-SPACe regime, use comparable no-fault allocation and insurance requirements, though the numbers and the indemnity limits differ. The UK, for example, works to a standard €60 million insurance requirement and indemnity limit for typical orbital operations, and the Space Industry (Indemnities) Act 2025, in force from 18 February 2026, now makes a liability cap mandatory in every operator licence rather than discretionary.

The short version

• The FCC replaced the 25 year post-mission disposal guideline with a five year maximum in Second Report and Order FCC 22-74, adopted 29 September 2022.
• It is codified at 47 CFR 25.283(e) and became effective 9 September 2024, with compliance required from 29 September 2024.
• It applies to spacecraft ending their mission in or passing through low Earth orbit below 2,000 km and planning uncontrolled reentry, including non-US systems granted US market access.
• Satellites already in orbit are grandfathered. Anything launched after 29 September 2024 is not.

For twenty five years the working number in orbital debris mitigation was twenty five years. A satellite in low Earth orbit was expected to clear the region within a quarter century of the end of its mission. That figure came out of NASA analysis in the 1990s and worked its way into the Inter-Agency Space Debris Coordination Committee guidelines, then into national practice.

It was a reasonable number for a world launching dozens of satellites a year. It is not a reasonable number for a world launching thousands.

What the rule says

The FCC’s Second Report and Order, FCC 22-74, was adopted on 29 September 2022 in IB Docket Nos. 18-313 and 22-271. The core change is short: for the spacecraft it covers, post-mission disposal must be completed as soon as practicable and no more than five years after the end of mission.

The obligation is codified at 47 CFR 25.283(e), with parallel amendments for experimental licences at 47 CFR 5.64 and amateur operations at 47 CFR 97.207.

Three limits on scope matter.

Orbit. It applies to space stations that will terminate their mission in, or pass through, low Earth orbit below 2,000 km, and that plan uncontrolled atmospheric reentry. Geostationary disposal continues to be handled by the graveyard orbit requirement, which is a separate obligation and the one DISH failed, as we discuss in our case note on that consent decree.

Reach. It applies both to systems licensed by the FCC and to non-US systems granted access to the US market. This is the important commercial point. A non-US constellation that wants to sell service in the United States takes on the obligation.

Timing. The order was adopted in September 2022 but the rule became effective on 9 September 2024 with compliance required from 29 September 2024, following the standard Paperwork Reduction Act sequence. Satellites already on orbit are exempt. Systems that were authorised but not yet launched had a two year grandfathering window running from adoption. Anything launched after 29 September 2024 complies or does not fly.

Why five years and not zero

Five years is not a physics number. It is a compromise between two positions.

Operators argued for a longer window on cost grounds. Deorbit capability is mass, mass is money, and for a cubesat the propulsion needed to guarantee a rapid deorbit can be a meaningful fraction of the spacecraft.

Debris researchers argued that even five years leaves a long tail. The relevant risk is not one dead satellite. It is the aggregate population of uncontrolled objects in the shells where constellations operate, and the probability that any two of them meet.

The Commission landed on five years plus a “as soon as practicable” obligation, which does real work. An operator that can deorbit in one year cannot elect to take five.

What it means for an application

For most operators the rule does not change the application form so much as the engineering that has to sit behind it. Three things need to be demonstrable at filing.

Disposal capability

Either propulsive deorbit, a drag device, or an orbit low enough that natural decay does the job inside five years. Natural decay is the cheapest route and it is why so many smallsat constellations cluster below about 550 km. Above roughly 600 km, passive compliance stops being realistic.

Reliability

The FCC expects a stated post-mission disposal reliability. If a percentage of the constellation is going to fail before disposal, that has to be in the analysis, and for large constellations a small failure rate is a large absolute number.

Casualty risk

Uncontrolled reentry raises human casualty risk on the ground. The working threshold used across the US agencies is one in ten thousand for a given reentry event, and design for demise is the usual answer.

Where the FCC has gone since

The five year rule now sits inside a much larger overhaul. In October 2025 the Commission proposed replacing Part 25 wholesale with a new Part 100, and on 22 July 2026 it adopted a Report and Order, FCC 26-47, doing exactly that.

The headline changes for operators are procedural rather than substantive on debris: a uniform 15 day public notice period, a 30 day deadline for the Commission either to put an application on public notice or say what is missing, a 60 day decision deadline after comments close, a stated presumption in favour of granting conforming applications, voluntary annual NGSO processing rounds, $10 million surety bonds for processing round applicants declining to zero at 90 percent deployment, and 20 year licence terms as standard.

Part 25 remains in force until the Space Bureau announces the effective date of Part 100 by public notice. Until then, cite Part 25.

The honest assessment

The five year rule is the most consequential unilateral debris measure any regulator has taken, and it was taken by a communications regulator using its licensing power rather than by a space agency or a treaty body. That is worth sitting with.

It also shows the limits of that route. The FCC can only reach systems it licenses or that want US market access. It cannot reach a constellation that never sells into the United States, and it has no jurisdiction over the objects already up there, which is where the accumulated risk lives.

The short version

• Part 450 has been the only route to a US launch or reentry licence since 10 March 2026, when the legacy Parts 415, 417, 431 and 435 were removed from the CFR.
• It is performance based. One licence can cover multiple vehicle configurations, mission profiles and sites.
• The FAA had issued 14 Part 450 licences as at March 2026.
• Two things changed the economics in 2026: a new per launch user fee, and a July 2026 proposal to waive NEPA and twelve other environmental statutes for launch licensing.

If a rocket leaves the ground from US territory, or a US company launches from anywhere, the FAA Office of Commercial Space Transportation has to have said yes first. The instrument is a vehicle operator licence under 14 CFR Part 450, and since March 2026 there is no alternative route.

That deadline mattered more than most regulatory transitions, because it retired four separate rule parts that some of the largest operators had been flying under for years.

What Part 450 replaced, and why

The Streamlined Launch and Reentry License Requirements rule was published on 10 December 2020 at 85 FR 79566 and took effect on 10 March 2021. It folded four regimes into one:

• Part 415, launch licences
• Part 417, launch safety
• Part 431, reusable launch vehicle mission licences
• Part 435, reentry

The old structure asked a different set of prescriptive questions depending on which box your vehicle fell into. If your vehicle did not fit a box, and by 2018 many did not, you negotiated waivers.

Part 450 replaced prescription with performance. Instead of telling an operator which specific analysis to run, the rule sets a safety outcome and asks the operator to propose a means of compliance. The FAA either accepts it or does not.

The commercial payoff is scope. A single Part 450 licence can authorise multiple vehicle configurations, multiple mission profiles and multiple launch or reentry sites. Under the old parts, a new site or a materially different mission often meant a new application.

The transition deadline that just passed

Operators holding legacy licences were given five years. All licences issued under Parts 415, 417, 431 and 435 expired by 9 March 2026, and the legacy parts came out of the Code of Federal Regulations on 10 March 2026.

Operators who completed the move include Blue Origin for New Shepard, Firefly for Alpha, SpaceX for Falcon 9, Falcon Heavy and Dragon, Rocket Lab for Electron, and ULA for Atlas and Vulcan. The FAA said in March 2026 that it had issued 14 Part 450 licences since the rule took effect.

Anyone still assuming a legacy path exists is working from stale material.

How the application is structured

Part 450 runs in five subparts, and it helps to think of them as stages rather than chapters.

Subpart C is where the work is. Section 450.101 sets the quantitative public safety criteria, expressed as collective and individual risk thresholds for the public, aircraft and ships. Everything downstream, the flight safety analysis, the hazard control strategies, the debris analysis, exists to demonstrate that those numbers are met.

The practical friction point is the means of compliance process. An operator proposes a method, the FAA accepts it, and only then can the analysis built on it be relied on. Applicants who leave means of compliance to the end of the drafting process lose months.

Financial responsibility runs in parallel

A Part 450 licence does not stand alone. Part 440 sits alongside it and sets the insurance obligation.

The FAA determines maximum probable loss, the greatest dollar amount of loss for bodily injury or property damage reasonably expected from the licensed activity, and issues a determination within 90 days of a complete request. The probability thresholds are one in ten million for third parties and one in one hundred thousand for government personnel and property.

Statutory caps sit above that: $500 million for third-party liability insurance and $100 million for government property, or the maximum available on the world market at reasonable cost if that is lower. Above the insured layer, 51 U.S.C. 50915 provides for government indemnification of up to $1.5 billion indexed from 1989, subject to appropriation that has never been made.

We walk through how that stack interacts with the contract in our piece on cross waivers and indemnification.

What changed in 2026

Launch user fees

The One Big Beautiful Bill Act, Pub. L. 119-21, added 51 U.S.C. 50924 on 4 July 2025. From 2026 there is a per launch or reentry fee, calculated as the lesser of a per pound of payload rate or an annual cap. For 2026 that is $0.25 per pound with a $30,000 cap, rising annually to $1.50 and $200,000 by 2033, then indexed to CPI.

The FAA’s implementing notice was published on 22 April 2026 under Docket FAA-2026-4170. Operators must supply payload weight at least 60 days before a mission and pay within 30 days of fee notification. For a heavy lift operator the cap makes this rounding error money. For a small launch operator flying frequently it is a line item worth modelling.

The environmental waiver proposal

The bigger story is procedural. On 30 July 2026 the FAA published an NPRM under Docket FAA-2026-8614, RIN 2120-AM51, that would insert a new section 400.3 disapplying thirteen environmental and resource protection statutes to launch and reentry licensing.

The list is not marginal. It includes NEPA, the Endangered Species Act, the Clean Water Act, the Clean Air Act, the Coastal Zone Management Act, the National Historic Preservation Act, the Marine Mammal Protection Act and the Magnuson-Stevens Act. The claimed authority is 51 U.S.C. 50905(b)(2)(C). Comments closed on 31 August 2026.

Environmental review has been the main source of delay and the main litigation surface for launch site expansion. If this rule is finalised in anything like its proposed form, that surface largely disappears, and the practical constraint on launch cadence shifts back to range availability and airspace.

It also runs in the same direction as the FCC’s proposal to treat space operations as extraterritorial and outside NEPA entirely, which we cover in our case note on the Dark-Sky litigation.

The Part 450 rewrite itself

An Aerospace Rulemaking Committee was chartered in November 2024 to recommend improvements to Part 450 across nine areas, including reentry operations, early test flights, means of compliance approval and the definition of safety critical systems. An executive order signed on 13 August 2025 directed the Secretary of Transportation to reevaluate and amend or rescind Part 450.

As at August 2026 no committee report and no amendment NPRM had appeared on the FAA’s rulemaking docket. Treat the substantive rewrite as still pre-proposal.

The learning period, correctly stated

Commentary routinely describes a “moratorium” on human spaceflight safety regulation. The statute is narrower than that.

Under 51 U.S.C. 50905(c)(9), beginning on 1 January 2028 the Secretary may propose occupant safety regulations without regard to the statutory restrictions in subparagraphs (C) and (D). The current date was set by Pub. L. 118-159 on 23 December 2024, the latest in a series of extensions running back to the 2004 Commercial Space Launch Amendments Act.

It restricts proposing regulations, and it is subject to triggers including a serious injury, fatality or high risk design event. It is not a blanket prohibition on the FAA acting.
