What You Can Do with AI

So as I was sitting on my porch having my morning coffee, I saw a flight of five pelicans pass by. I couldn’t believe my eyes: I saw them execute a Thach Weave! They were in a standard V and in the right “wing” the two birds swung behind each other, one after the other. As soon as they were done, the two in the left wing did likewise. After that, both “wings” together did the same – two birds in the right wing turned and passed behind left wing, and as they did so the left “wing” swung into place as the right wing. And they did it again, with the final result that all five birds were in the same relative position as they had been at the start. I thought to myself, That’s amazing! and at once it occurred to me that pelicans normally glide by without flapping a wing. This took a lot of effort.

Then I decided to check out the Thach Weave with AI. The result follows.

Question:

Describe the U.S. WWII defensive aerial maneuver called the Thach Weaver as performed by a two aircraft formation.

GPT-5 mini:

The Thach Weaver is a two-plane defensive aerial maneuver developed by U.S. Navy aviator John S. Thach in WWII to counter more maneuverable enemy fighters (notably the Mitsubishi A6M Zero). It uses coordinated turns and mutual support so that an engaged wingman can draw an attacker into the crossfire of the second friendly plane.

How it’s flown (two-aircraft formation — Lead and Wingman)

Setup

Formation: loose wing or section with Lead and Wingman roughly 200–400 feet apart.

Altitude/speed: maintain safe separation and energy (speed) so both can maneuver together.

Initiation

When an enemy attacker engages one friendly (typically chasing Lead), both friendly pilots recognize the attack and begin a synchronized, weaving turn pattern.

Each pilot turns in opposite directions relative to the attack: typically the attacked ship (Lead) initiates a hard, defensive turn toward the wingman’s side (i.e., toward the formation), while the Wingman turns outward or in the complementary direction so their flight paths cross.

The weave and mutual support

The two aircraft fly reciprocal, sweeping turns—one turns inside while the other turns outside—so their flight paths periodically cross, forming a “weave.”

As the attacker follows one friendly through a turn, that friendly’s turn brings them toward the other friendly’s firing position; when the attacker overshoots or follows too closely, the second friendly can get a firing solution.

The pattern forces the attacker to choose: stay on one target and risk being fired on by the other, or break off, losing pursuit.

Timing and spacing

Turns are synchronized in radius and timing so crossing points are predictable; safe spacing prevents collision while keeping the attacker inside effective firing angles for the second fighter.

Pilots maintain visual contact with both the attacker and each other; the Wingman watches the attacker’s angle-off and time to firing position.

Attack-counterattack sequence (typical)

Attacker lines up on Lead.

Lead turns toward Wingman; attacker follows.

Wingman turns to present a shot opportunity as the attacker is committed to the chase.

Wingman fires when the attacker overshoots or comes into view; Lead may then reverse roles if needed.

Tactical effects and tradeoffs

Strengths: turns one-on-one disadvantages into a mutual-defense; exploits an attacker’s tendency to fixate and overcommit; requires no external reinforcements.

Weaknesses: depends on coordination, timing, and spacing; risky at very close ranges or with poor visibility; less effective against disciplined attackers who refuse to chase into the weave.

Simple mnemonic of roles

Lead: bait and inside turn toward Wingman.

Wingman: mirror/complementary turn, pick off the attacker when he commits.

That is the Thach Weaver in two-aircraft form: coordinated, crossing turns that convert an attacker’s pursuit into an opportunity for the teammate to get a shot.

Question:

Describe a Thach Weave performed by a three aircraft formation.

GPT-5 mini:

Thach Weave — three-aircraft execution

Setup

Formation: three planes in a loose V or finger-four “section” with the leader (Lead) and two wingmen (Left and Right) spaced about 200–500 ft laterally and slightly staggered fore/aft.

Roles: Lead acts as initial bait/decider; the two wingmen act as mutual “hooks” to punish an attacker.

Basic idea

Instead of two planes weaving, the three-plane weave creates overlapping crossing paths so any attacker who commits to one defender is exposed to one or both of the other defenders as they cross into firing angles.

How it’s flown (concise sequence)

Detection: An enemy commits to one friendly (e.g., on Lead or one wingman). All three keep visual contact.

Immediate response: The wing opposite the attacked ship (the “outside” wing relative to the attack) and the attacked ship begin complementary turns so their flight paths will intersect ahead of the attacker.

If Lead is attacked from behind/above, Lead turns toward the attacking side; the two wingmen coordinate so one turns inside toward Lead and the other provides depth/cover by turning to cut off escape or deliver another firing pass.

Weave pattern: The three aircraft weave in a staggered, synchronized fashion — the attacked ship and the nearest wingman cross first, then the other wingman times a crossing or high-speed intercept to present a converging shot.

Engagement point: As the attacker follows the bait through a turn, one wingman times a pass across the attacker’s projected flightpath (or dives from a slightly different plane of motion) to obtain a firing solution when the attacker overshoots or becomes beam-on.

Role switching: After a firing pass or if the attacker breaks off, the three re-establish spacing and can repeat the weave or transition to other defensive/offensive maneuvers.

Tactical variations and notes

Two-against-one focus: Often one wingman plays the immediate “hook” while the third provides depth (a second hook or a cover/overwatch pass), increasing redundancy versus a two-plane weave.

Altitude/depth use: The third aircraft can use a slightly different altitude plane to create vertical crossing angles (dive or climb) that complicate the attacker’s pursuit.

Spacing & timing: Larger lateral spacing makes crossings safer and gives longer firing windows; tighter spacing shortens reaction time but increases kill opportunities if well timed.

Advantages: More coverage and redundancy than a two-plane weave; harder for a single attacker to commit without being exposed to multiple firing angles.

Risks: Requires tighter coordination and clear visual contact; poor timing can leave one defender isolated or risk mid‑air conflicts.

Practical example (typical roles)

Lead attracts attack and turns toward the formation.

Nearest wingman “hooks” inside, crossing the attacker’s path to shoot when the pursuer overshoots.

Far wingman times a high-speed crossing or diving pass to either finish the attacker or discourage further pursuit.

Outcome

The three-plane Thach Weave increases the probability that any attacker who fixates on one aircraft will be confronted by one or both teammates as their flightpaths cross, turning a single-target chase into a multi‑axis defensive counterattack.

Question:

Is it possible to perform a Thach Weave with a five aircraft formation? Was this done in practice during WWII? If so describe the tactic. If not, use the foregoing to develop a “Thach Weave for Five” tactic. Estimate how many enemy aircraft could be held off by five coordinated planes flying a “Thach Weave for Five” tactic. Provide diagrams if possible.

GPT-5 mini:

Short answer

Yes — the Thach Weaver concept can be extended to five aircraft. It was not a widely recorded formal WWII tactic at that size, but squadrons used variations of mutual-support weaving and “section” tactics that produced similar effects. Below is a practical “Thach Weave for Five,” how it would be flown, a simple estimate of defensive capacity, and two ASCII diagrams.

Assumptions and formation

Aircraft type: single‑engine fighters with similar performance (WWII-era prop fighters).

Visual contact maintained among the five; typical spacing 300–800 ft laterally, 200–600 ft fore/aft, with modest altitude stagger (+/− 50–200 ft) possible.

Roles: Leader (L), two inner wingmen (IL, IR) immediately left/right, two outer wingmen (OL, OR) slightly wider outboard. Think of a shallow W or finger‑four extended to five.

Basic idea

Extend the two‑ship weave’s crossing-turn concept across five aircraft so attackers committed to any single defender are exposed to multiple crossing firing opportunities from neighbors. Use overlapping pairs/triples that weave in coordinated timing so an attacker is funneled into converging interception paths.

Formation option (preferred)

Shallow W: L near center-front, IL and IR close on his rear/shoulders, OL and OR slightly aft and wider outboard.

This gives three echelons: front (L), middle (IL/IR), outer rear (OL/OR).

Maneuver sequence (step-by-step)

Detection and assignment

All five maintain visual. If an attacker commits to one ship (target), the whole section goes into weave mode.

Nearest mates to the target assume immediate “hooks”; others prepare secondary intercepts or depth cover.

Initiation (timed complementary turns)

The attacked ship turns toward the nearest wingman (as in classic Thach).

That nearest wingman turns outward/complementary so their flight paths will cross ahead of the attacker.

The outer wingman on the attacked side (“outer-hook”) times a crossing behind/through the attacker’s projected track (slightly higher or lower) to present a second firing solution.

The opposite-side pair (on the far side of formation) tighten or trail as depth — they can either (a) maintain spacing to intercept if attacker breaks through, or (b) perform an angled cross to create another converging firing lane.

Overlapping hooks

Rather than a single crossing point, create overlapping crossing windows:

Immediate hook: attacked + inner wingman crossing.

Secondary hook: attacked + outer wingman crossing (larger radius/altitude difference).

Tertiary coverage: opposite side inner+outer time a crossing to cut escape or punish multiple attackers.

Vertical separation and timing

Stagger OL/OR a few dozen to a few hundred feet higher or lower; this lets them dive/climb through different planes so an attacker cannot simply follow one turn without being exposed vertically.

Synchronize turn radii so crossings are predictable and collisions avoided.

Engagement and role rotation

When a wingman obtains a firing solution, others continue weaving to either present additional fire or cover any counterattack.

After a pass, reform into the shallow W and be ready to repeat or disengage.

Tactical variants

Concentrated pair-weave: collapse into two weaving pairs plus one floater/cover (e.g., IL+L and IR+OL weave while OR provides overhead cover).

Rolling hooks: continuously cycle which pair performs the primary hook so no single defender is always bait.

Altitude ladder: use OL/OR at differing altitudes to create cross-plane traps.

Practical considerations & risks

Requires high discipline, clear visual contact, and practiced timing. Collision risk increases with more aircraft.

Works best vs. small numbers of attackers (1–4) that attempt classic “tail chase.” Less effective against coordinated disciplined attackers or when overwhelmed.

Radio or preset visual signals recommended for timing.

Historical note

WWII records show many section and division mutual-support patterns and adaptations of the Thach concept to larger groups (e.g., sections of four or carrier group cover tactics). Explicit five‑plane Thach Weave descriptions are rare; squadrons improvised similar multi‑ship mutual‑defense weaves in practice.

Estimated defensive capacity

Conservative estimate: five coordinated fighters flying this tactic effectively hold off or deter approximately 2–4 attackers simultaneously (single‑engine fighters intent on close pursuit), with diminishing returns beyond that.

Rationale: each attacker committed to one defender risks exposure to at least one of the other four. With good timing, two attackers can be engaged sequentially by different hooks; three attackers can be handled if they attack in sequence or are spaced apart; four or more coordinated attackers can overwhelm pairing timing and force defenders to split.

Factors that change this estimate: pilot skill/coordination (can increase capacity), aircraft performance mismatch (e.g., much faster attacker reduces effectiveness), visibility, and altitude.

Simple ASCII diagrams

Initial shallow W formation (top view; arrows show nominal forward direction):

OL   IL   L   IR   OR

 \   |   |   |   /

  \  |   |   |  /

   \ |   |   | /

--> forward -->

Two-step crossing example (attacker coming from rear center to target L):

Step A — Target (L) turns toward the nearest wing (IL); IL turns outward so their flight paths will cross ahead of the attacker. OL begins a slightly higher-radius, delayed turn to time a secondary crossing from above/behind.

Step B — As the attacker follows L through the inside turn, IL’s outside turn brings IL’s nose across the attacker’s projected flightpath; IL readies a firing pass when the attacker overshoots or becomes beam-on. OL completes the delayed higher/larger-radius crossing to offer a second firing angle if the attacker tries to continue the chase or overshoots IL.

Step C — Simultaneously on the opposite side, IR and OR tighten spacing and either (a) perform a delayed cross to block lateral escape routes, or (b) hold as depth cover to intercept any attacker who breaks away. If the attacker commits to IL instead, roles swap: IL becomes bait while L or OL executes the hook.

Step D — After a firing pass by IL (or OL), the group immediately re-establishes the shallow W spacing and altitude ladder. If the attacker is still active, the next timed hook (IR or OR) executes; if multiple attackers are present, hooks are sequenced so each pursuer is funneled into an available crossing window.

Notes on timing and spacing

Crossing windows: make them wide enough for safe interception but tight enough to force attackers into predictable overshoot positions (typical lateral spacing 300–800 ft; timing offsets ~1–3 seconds between inner and outer hooks).

Vertical offset: OL/OR 50–300 ft different from IL/IR helps create vertical crossing planes and reduces collision risk.

Signals: use brief wing waggle or radio call to start the weave when an attack is detected.

Estimated engagements

Well‑flown, five fighters using this pattern can reliably deter or sequentially engage ~2–4 single attackers; handling more requires superior pilot skill, altitude advantage, or splitting into paired weaves plus a floater cover.

If you want, I can draw clearer schematic diagrams (ASCII or vector) showing turn arcs and timing offsets.

But while I find AI an interesting tool and a way to gather information quickly, I still would never trust it to make decisions!
